The p-value for a sample of different sales promotions with 5 different promotions and 10 samples with all 5 is equals to the 0.1060.
Suppose that the sales manager wants to compare different sales promotions. Here, number of different promotion choosen by him = 5
Number of random sample of each different promotion= 10
The F value = 3.4
We have to determine the p-value by using JMP. Now, n = 10, k = 5 so, degree of freedom = n - k= 5
Computing the p value using approximate method, [tex]P-value = P( F_{k - 1, n-k} > 3.4 ) [/tex]
[tex]= P( F_{4, 5}> 3.4 ) [/tex]
Using Excel command, value of F is calculated, = F.dist.RT( 3.4,4,5)
= 0.105954
Hence, required value is 0.1060.

Determine how many terms of the following convergent series must be summed to be sure that the remainder is less than 10−2
[infinity]∑k=1(−1)k+1k4
There are 16 terms of the convergent series must be summed to be sure that the remainder is less than 10⁻²[infinity]∑k=1(−1)k+1k4
The alternating series estimation theorem can be used to determine an upper bound for the error in approximating the total of the series by summing a finite number of terms. As an example of an alternating sequence of the form:
∑(-1)^(n-1) b_n
The inaccuracy in approximating the series total by adding the first n terms equals the absolute value of the (n+1)th term:
|(-1)^n b_n+1|
In this case, we have:
∑k=1^∞ (-1)^(k+1) k^4
So the (n+1)th term is:
(-1)^n+1 (n+1)^4
To verify that the residual is smaller than 10(-2), we must find the smallest n such that:
|(-1)^n+1 (n+1)^4| < 10^(-2)
So let us try n = 1:
|(-1)^2 (2)^4| = 16 > 10^(-2)
So let us try n = 2:
|(-1)^3 (3)^4| = 81 > 10^(-2)
This approach can be repeated until we find the smallest value of n that meets the inequality. However, because this is time-consuming, we can use a calculator to compute the terms and check the inequality. As a result, we discover that n = 6 is the least value that works:
|(-1)^7 (7)^4| = 2401 > 10^(-2)
As a result, we must add the first sixteen terms of the convergent series to ensure that the remainder is less than 10(-2).

Exercise 1. Consider a Bernoulli statistical model, where the probability of a success is the parameter of interest and there are n independent observations x =\ x 1 ,...,x 1 \ where x_{i} = 1 with probability 0 and x_{i} = 0 with probability 1 - theta Define the hypotheses H_{0} / theta = theta_{0} and H_{A} / theta = theta_{A} and assume alpha = 0.05 and theta_{0} < theta_{A}
(a) Use Neyman-Pearson's lemma to define the rejection region of the type n overline x > kappa
(b) Let n = 20 theta_{0} = 0.45 , theta_{A} = 0.65 and sum i = 1 to n x i =11 Decide whether or not H_{0} should be iid rejected. Hint: use the fact that n overline X sim Bin(n, theta) when Bernoulli (0). [5]
(a) the rejection region is n overline x > kappa.
(b) kappa = 13/20 = 0.65. Since n overline x = 11 > kappa, we reject the null hypothesis and conclude that there is evidence in favor of the alternative hypothesis that theta > 0.45.
What is hypothesis?
A hypothesis is a proposed explanation or tentative answer to a research question or phenomenon. The null hypothesis is the default position that there is no significant difference between two groups or variables, while the alternative hypothesis proposes that there is a significant difference.
(a) According to Neyman-Pearson's lemma, the likelihood ratio is the most powerful test for a simple vs. a composite hypothesis. The likelihood function for the Bernoulli distribution is:
[tex]L(\theta | x) = \theta^k (1 - \theta)^{(n-k)[/tex]
where k is the number of successes in n trials. The likelihood ratio is:
[tex]\Lambda(x) = L(\theta_A | x) / L(\theta_0 | x)[/tex]
[tex]= (\theta_A^k (1 - \theta_A)^{(n-k)}) / (\theta_0^k (1 - \theta_0)^{(n-k)})[/tex]
Taking the logarithm and simplifying, we get:
[tex]log \Lambda(x) = k log(\theta_A / \theta_0) + (n-k) log((1 - \theta_A) / (1 - \theta_0))[/tex]
To define the rejection region, we need to find the value of kappa such that [tex]P(n overline x > kappa | \theta = \theta_0)[/tex] = alpha, where overline x is the sample mean. Since n overline x sim Bin(n, theta_0), we have:
[tex]P(n overline x > kappa | \theta = \theta_0) = 1 - P(n overline x < = kappa | \theta = \theta_0)\\= 1 - F(n overline x < = kappa | \theta = \theta_0)\\= 1 - sum from i=0 to floor(kappa*n) (n choose i) (\theta_0^i) ((1-\theta_0)^(n-i))[/tex]
where F is the cumulative distribution function of the binomial distribution. We can use a numerical method or a table to find kappa such that [tex]P(n overline x > kappa | \theta = \theta_0) = \alpha.[/tex]
Therefore, the rejection region is n overline x > kappa.
(b) Using the given values, we have k = 11, n = 20, [tex]\theta_0 = 0.45[/tex], and [tex]\theta_A = 0.65[/tex]. The sample mean is overline x = k/n = 0.55. To find kappa, we need to solve:
[tex]P(n overline x > kappa | \theta = \theta_0) = alpha\\1 - F(n overline x < = kappa | \theta = \theta_0) = 0.05\\F(n overline x < = kappa | \theta = \theta_0) = 0.95[/tex]
Using a binomial table, we find that the 0.95th percentile of the binomial distribution with n = 20 and theta = 0.45 is 13. Therefore, kappa = 13/20 = 0.65. Since n overline x = 11 > kappa, we reject the null hypothesis and conclude that there is evidence in favor of the alternative hypothesis that theta > 0.45.

Answer:
56°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°.
The triangle shown in the image is a right triangle so one of the angle measure is 90°.
Given, the other angle is 34°, we can find the value of missing angle with the following equation:
Let x represent the missing angle.x + 90° + 34° = 180°
Add like terms.x + 124° = 180°
Subtract 124 from both sides.x = 56°

V = 3.14*3²*2 = 56.52 units³Suppose a researcher were to take repeated random samples of size n=144 from the population described in the previous question, calculating the mean level of education in the sample each time. In what range would 95% of the sample means fall? Now suppose the researcher has just one sample of size n=144 and does not know the true mean or standard deviation of education in the population. In the sample, the standard deviation of education is 2.4 and the mean is 12.35 years. Construct and provide the 95% confidence interval around the sample mean. Is the true population mean contained in this interval?
The true population mean of 12.5 years falls within this interval, we can say with 95% confidence that the true population mean is contained in this interval.
As the population in the previous question is normally distributed with a mean of 12.5 years and a standard deviation of 2 years, the standard error of the mean (SEM) can be calculated as:
SEM = standard deviation / sqrt(sample size) = 2 / sqrt(144) = 0.17
Therefore, the 95% confidence interval for the sample mean can be calculated as:
sample mean ± 1.96 * SEM
= 12.35 ± 1.96 * 0.17
= [12.02, 12.68]
This means that if the researcher were to take repeated random samples of size 144 from the population and calculate the mean level of education in each sample, 95% of those sample means would fall within the range of 12.02 to 12.68 years.
Now, for the second part of the question, the 95% confidence interval for the population mean can be constructed as:
sample mean ± (critical value * SEM)
where the critical value for a 95% confidence interval with 143 degrees of freedom is 1.98 (obtained from a t-distribution table).
Therefore, the 95% confidence interval for the population mean is:
12.35 ± (1.98 * (2.4 / sqrt(144)))
= [12.00, 12.70]
Since the true population mean of 12.5 years falls within this interval, we can say with 95% confidence that the true population mean is contained in this interval.

The mean of the dot plot can be found as follows;
Mean = (3 + 2 × 5 + 4 × 7 + 3 × 9 + 2 × 11)/(1 + 2 + 4 + 3 + 2) = 7.5
Therefore, the sum of the values = (3 + 2 × 5 + 4 × 7 + 3 × 9 + 2 × 11) = 90

Determine over what interval(s) (if any) the Mean Value Theorem applies. (Enter your answer using interval notation. If an answer does not exist, enter DNE.)
y=√x2−25
The Mean Value Theorem applies over the interval (-5, 5) and (5, ∞).
To determine the interval(s) where the Mean Value Theorem (MVT) applies for the function y=√(x^2-25), we need to ensure that the function is continuous and differentiable on the given interval.
1. The function is continuous when the expression under the square root is non-negative, which means x^2-25≥0. Solving for x, we get x≥5 or x≤-5. In interval notation, the domain for continuity is (-∞,-5] U [5,∞).
2. To check for differentiability, we need to find the derivative of the function. The derivative of y=√(x^2-25) is:
y' = (1/2)(x^2-25)^(-1/2) * 2x
y' = x/√(x^2-25)
Now, we need to ensure that the derivative is defined on the given interval. Since x=5 or x=-5 makes the denominator zero, we should exclude these points. Hence, the interval for differentiability is (-∞,-5) U (5,∞).
Since the MVT requires both continuity and differentiability, the applicable interval(s) for the Mean Value Theorem are (-∞,-5) U (5,∞).

find a polynomial function of lowest degree with rational coefficients that has the given numbers as some of its zeros. -3i,5
To find a polynomial function of the lowest degree with rational coefficients and given zeros -3i and 5, we first need to remember that complex zeros always come in conjugate pairs. Since -3i is one of the zeros, its conjugate 3i is also a zero.
Now, let's find the polynomial using these zeros: (x - (-3i))(x - 3i)(x - 5). We can rewrite this as:
(x + 3i)(x - 3i)(x - 5)
Now, let's multiply the first two factors:
(x^2 - 3ix + 3ix + 9) (x - 5)
Simplifying this gives us:
(x^2 + 9)(x - 5)
Now, let's multiply this with the remaining factor:
x^3 - 5x^2 + 9x - 45

a 10-segment trapezoidal rule is exact to find integrals of polynomials of order ________ or less
A 10-segment trapezoidal rule is exact to find integrals of polynomials of order 3 or less. Here's a step-by-step explanation:
1. The trapezoidal rule is a numerical integration method used to approximate the integral of a function.
2. It works by dividing the area under the curve of the function into a series of trapezoids and then summing their areas.
3. The number of segments (trapezoids) determines the accuracy of the approximation. In this case, we have 10 segments.
4. The trapezoidal rule is exact for polynomials of order 1 (linear functions) because the area under the curve of a linear function can be exactly represented by trapezoids.
5. However, the trapezoidal rule can also provide exact results for higher-order polynomials in certain cases. For a 10-segment trapezoidal rule, it turns out to be exact for polynomials of order 3 or less.

Find an interval of t-values such that c(t) = (cos t, sin t) traces the upper half of the unit circle (in the counter-clockwise direction), interval = Note: Use lowercase "pi" for pi. Example answer: [0,1 ].
The interval of t-values such that c(t) = (cos t, sin t) traces the upper half of the unit circle (in the counter-clockwise direction) is [0, pi].
To see why this is the case, recall that the unit circle is given by the equation x^2 + y^2 = 1, where (x,y) are the coordinates of a point on the circle. The upper half of the unit circle corresponds to the set of points (x,y) where y is positive or zero. We want to find the values of t for which c(t) lies on the upper half of the unit circle.
Using the definition of c(t), we have c(t) = (cos t, sin t). The y-coordinate of c(t) is sin t, so we want, sin t to be positive or zero. Since sin t is positive in the first and second quadrants of the unit circle, and zero at t = 0 and t = pi, we have that c(t) traces the upper half of the unit circle when t is in the interval [0, pi].
To see that c(t) traces the upper half of the unit circle in the counter-clockwise direction, note that as t increases from 0 to pi, c(t) moves counterclockwise around the unit circle, starting at (1,0) and ending at (-1,0). Thus, the interval [0, pi] corresponds to one-half of a full counterclockwise rotation around the unit circle, which is exactly the upper half of the circle.
