in order to develop an interval estimate of a population mean, the margin of error must be computed using:
In order to develop an interval estimate of a population mean, the margin of error must be computed using: either population standard deviation, σ or the sample standard deviation, s.
What is the margin of error?In Mathematics, the margin of error (MOE) can be defined as a measure of the difference that exist between an observed value and a true value of the population parameter.
This ultimately implies that, the margin of error (MOE) can be used to determine the confidence interval.
How to determine the sample size?In Mathematics and Statistics, a sample size that would result in a specific standard deviation can be calculated by using the following mathematical equation (formula):
Sample size, n = (zσ/ME)²
Where:
n represents the sample size.z represents the z-score of the desired confidence level. σ represents the standard deviation of the population.ME represents the margin of error.Read more on sample size here: brainly.com/question/30520316

the ages of all the patients in the isolation ward of the hospital are 38, 26, 13, 41, and 22. what is the population variance?multiple choice106.8240.391.442.4
106.8 is the population variance.
To calculate the population variance, we use the formula:
[tex]s^{2}[/tex] = Σ [[tex](xi-u)^{2}[/tex]] / N,
where xi is the ith observation, u is the population mean, and N is the population size.
First, we need to calculate the population mean:
u = (38 + 26 + 13 + 41 + 22) / 5 = 28.
Next, we calculate the sum of squares:
Σ [[tex](xi-u)^{2}[/tex]] = [tex](38-28)^{2}+ (26-28)^{2}+(13-28)^{2}+(41-28)^{2}+(22-28)^{2}[/tex]
= 100 + 4 + 225 + 169 + 36
= 534.
Finally, we divide by the population size:
[tex]s^{2}[/tex] = Σ [[tex](xi-u)^{2}[/tex]] / N = 534 / 5 = 106.8.
Therefore, the population variance is 106.8.
The closest choice to this answer is 106.8, which is the first option. So the answer is 106.8.

a football quarterback has 2 more chances to throw a touchdown before his team is forced to punt the ball. he misses the receiver on the first throw 40% of the time. when his first throw is incomplete, he misses the receiver on the second throw 15% of the time. what is the probability of not throwing the ball to a receiver on either throw? (10 points)
The probability of not throwing the ball to a receiver on either throw is 0.66, or 66%.
Consider two conceivable scenarios for quarterback tosses.
1. He tosses the ball to the recipient on his to begin the endeavor.
2. He misses the collector on his to begin with endeavor and once more on his moment endeavor.
The likelihood of situation 1 is 1 – 0.4 = 0.6. Usually since the quarterback on the primary attempt he misses the collector 40% of the time.
The likelihood for Situation 2 can be calculated as
P(1st Endeavor Fizzled + 2nd Endeavor Fizzled) = P(1st Endeavor Fizzled) * P(2nd Endeavor Fizzled | 1st Endeavor Fizzled)
= 0.4 * 0.15 = 0.06
Subsequently, the likelihood of not tossing the ball to the recipient on any toss is the entirety of the probabilities of Scenarios 1 and 2.
P(Don't toss to recipient) = P(Scenario 1) + P(Scenario 2)
= 0.6 + 0.06
= 0.66
Hence, the likelihood of not tossing the ball to the collector on any toss is 0.66, or 66%.

Select the correct answer. Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second? A. 15 + d = 100 B. 100 + d = 15 C. d × 15 = 100 D. d × 100 = 15
Answer:
To find the equation for d, the distance in meters that Martin covers per second, we need to use the formula:
distance = speed × time
Here, the distance covered by Martin is 100 meters, and the time taken is 15 seconds. Therefore, we can write:
distance = speed × time
100 meters = speed × 15 seconds
To find the speed, we can rearrange the equation as:
speed = distance / time
speed = 100 meters / 15 seconds
So the speed of Martin is:
speed = 6.67 meters per second
Therefore, the correct equation for d, the distance in meters that Martin covers per second, is:
d = speed
d = 6.67 meters per second
Answer: There is no option that matches the correct equation for d, which is simply d = 6.67 meters per second.

Reflexive Property
The reflexive property of equality in algebra asserts that a number is always equal to itself. Equality has a reflexive attribute. If an is a positive integer, then a = a.
When two parallel lines cross by any other line (i.e. the transversal), corresponding angles are generated in matching corners or corresponding angles with the transversal.
So in the above proof, ∠4 ≅ ∠1 ; ∠3≅∠2 because they are a pair of corresponding angels because they are created in matching corners.

The sample size for estimate the proportion of families in a certain area that are living below the poverty level is equals to the 318.75.
The standard error is a statistic term that is the standard deviation of its sampling distribution or an estimate of that standard deviation. In case of sample mean, it is called the standard error of the mean. Formula of standard mean is
[tex] SE =\sqrt{ \frac{\hat p (1 - \hat p)}{n}} [/tex]
where, n--> sample size
We have a simple random sample for estimate the proportion of families,
Sample proportion = 0.15
Standard error = 0.02
We have to determine the sample size for the standard error of the estimate is .02.
Here, SE = 0.02, \hat p = 0.15
Using the standard score formula,
[tex] 0.02 =\sqrt{ \frac{0.15 (1 - 0.15)}{n}} [/tex]
Squaring both sides
[tex] 0.02² = \frac{0.15 ×0.85 }{n} [/tex]

What is simple interest?
A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,
we know that the cost for an adult was not changed in May. Therefore, we can set the original cost equal to the new cost:
x = $22.10
Substituting this value in the equation above, we get:
$22.10 = 22.10 * (100/ (100-p))
Simplifying the equation, we get:
1 = 100 / (100-p)
Multiplying both sides by (100-p), we get:
100-p = 100
Therefore, p = 0.
So, the percentage reduction in cost is 0%, which means there was no reduction in cost for adults.

The height of the clock tower in Sara's drawing is 16.5 centimeters.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
The scale factor is 12 feet per 2 centimeters, which simplifies to 6 feet per 1 centimeter.
First, we need to figure out how many centimeters on Sara's drawing represent one foot:
2 cm : 12 ft
We can simplify this ratio by dividing both sides by 2:
1 cm : 6 ft
Now we can use this ratio to find the height of the clock tower in centimeters:
99 ft × (1 cm/6 ft) = 16.5 cm

Finding the number of fruit bars:The problem involves finding the number of fruit bars left after a certain fraction has been consumed and then calculating how much of the remaining fruit bars were taken home using another fraction.
Here we have
Eliza brought 6 pans of homemade fruit bars to school.
Her classmates ate 5/12 of each pan.
The total amount of fruit bars they consumed is:
=> 6 pans x 5/12 = 2.5 pans
So Eliza had 6 - 2.5 = 3.5 pans of fruit bars left.
Eliza gave 1 whole pan of the leftover fruit bars to the school's secretaries and took the rest home.
Leftover bars = 3.5 pans - 1 pan = 2.5 pans
To find the number of the fruit bars she took home, multiply the number of pans by the amount that wasn't eaten, which is:
=> 2.5 pans x 7/12 = 35/24 pans

y = 6(2)-11
y = 12-11
y = 1
The solution is (2, 1)
2) 2x-3y = -1......(i)
y = x-1.........(ii)
Solution -
Put eq(ii) in eq(i),
2x-3(x-1) = -1
2x-3x+3 = -1
-x = -4
x = 4
Put x = 4, in eq(ii)
y = 4-1
y = 3
The solution is (4, 3)
Hence, the solution of the given system of equations are 1) (2, 1) and 2) (4, 3)

how much glass is needed to cover the entire pyramid?
Answer:
2nd choice: 144.53 ft²
Step-by-step explanation:
Area of base = 6 x 7 = 42
Area of 2 sides with 8 ft height = 2 · (1/2)(6)(8) = 48
Area of 2 sides with 7/79 ft height = 2 · (1/2)(7)(7.79) = 54.53
Total SA = 42 + 48 + 54.53 = 144.53 ft²
