When the population standard deviation is known, the confidence interval for the population mean is based on the z-statistic.

When the population standard deviation is known, the confidence interval for the population mean is based on the z-statistic.

The formula for the confidence interval for the population mean when the population standard deviation is known is given by:

CI = X ± z(α/2) * σ/√n

Where:

X is the sample mean

σ is the population standard deviation

n is the sample size

z(α/2) is the z-score corresponding to the desired level of confidence (e.g. for a 95% confidence interval, α = 0.05 and z(α/2) = 1.96)

The z-statistic is used in this formula to determine the width of the confidence interval. It is based on the standard normal distribution and represents the number of standard deviations the sample mean is from the population mean. The z-score is calculated using the formula:

z = (X - μ) / (σ/√n)

Where μ is the population mean.

The z-score is used to find the critical values for the confidence interval, which are obtained by multiplying it by the standard error of the mean (σ/√n). These critical values define the endpoints of the confidence interval.

In summary, when the population standard deviation is known, the confidence interval for the population mean is based on the z-statistic, which is used to calculate the critical values for the confidence interval.

We can see that 7/4 is located between 3/4 and 1 on the first interval, and 9/4 is located between 2 and 5/2 on the second interval.

To partition each whole number interval into fourths, divide each interval by 4. Label 7/4 between 3/4 and 1 and label 9/4 between 2 and 5/2 on an extended scale from 0 to 3.

To partition each whole number interval into fourths, we can divide each interval by 4. For example, the interval from 0 to 1 can be divided into fourths as follows:

0 -------- 1/4 -------- 1/2 -------- 3/4 -------- 1

Now, to label 7/4 and 9/4 on this scale, we can extend it by adding another interval from 1 to 2 and dividing it into fourths as well. This would give us the following scale:

0 -------- 1/4 -------- 1/2 -------- 3/4 -------- 1 -------- 5/4 -------- 3/2 -------- 7/4 -------- 2 -------- 9/4 -------- 5/2 -------- 11/4 -------- 3

∠ PQR = 18°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ PQR is an exterior angle of the triangle , then

∠ PQR = ∠OPQ + ∠ QOP , that is

4x - 10 = x + 9 + x - 5

4x - 10 = 2x + 4 ( subtract 2x from both sides )

2x - 10 = 4 ( add 10 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Step-by-step explanation:

Since d satisfies all three properties of an equivalence relation, we conclude that d is indeed an equivalence relation on Z.

To prove that d is an equivalence relation on Z, we need to show that it satisfies three properties: reflexivity, symmetry, and transitivity.

Reflexivity: For any m ∈ Z, we have [tex]m^2 - m^2[/tex] = 0, which is divisible by 3. Therefore, m is related to itself under d, so d is reflexive.

Symmetry: If m d n, then [tex]3 | (m^2 - n^2)[/tex]). This means that there exists an integer k such that [tex]m^2 - n^2 = 3k.[/tex]

Rearranging this equation, we get n^2 - m^2 = -3k, which implies that 3 divides (n^2 - m^2) as well. Therefore, n d m, and d is symmetric.

Transitivity: Suppose m d n and n d p. Then, we have [tex]3 | (m^2 - n^2)[/tex] and [tex]3 | (n^2 - p^2)[/tex].

Adding these two equations, we get   [tex]3 | ((m^2 - n^2) + (n^2 - p^2)),[/tex], which simplifies to [tex]3 | (m^2 - p^2).[/tex] Therefore, m d p, and d is transitive.

Since d satisfies all three properties of an equivalence relation, we conclude that d is indeed an equivalence relation on Z.

The angular velocity of the circle is approximately 19 m/s.

In order to find the missing quantity, we can use the relationship between linear velocity and angular velocity in a circle. The linear velocity of a point on the edge of a circle is the product of the radius and the angular velocity. This can be expressed as:

v = r * w

where v is the linear velocity, r is the radius, and w is the angular velocity.

To find the value of w, we can rearrange this equation to solve for w:

w = v / r

Substituting the given values of v and r, we get:

w = 1235 m/min / 65 m

w = 19 m/s

It's important to note that units must be consistent when using formulas to solve problems. In this case, we converted the given linear velocity from m/min to m/s before plugging it into the formula.

The probability that the subject actually has an IQ below 150 given that they are labeled as having an IQ over 150 is approximately 0.00073276, or 0.07328% when rounded to five decimal places.

Let's use Bayes' theorem to solve the problem. Let A be the event that the subject has an IQ over 150, and B be the event that the subject actually has an IQ below 150. We want to find P(B|A), the probability that the subject has an IQ below 150 given that they are labeled as having an IQ over 150.

From the problem, we know that P(A) = 1/1100, the probability that a random person has an IQ over 150. We also know that P(A|B') = 0.0008, the probability that someone with an IQ below 150 is labeled as having an IQ over 150 due to lucky guessing.

To find P(B|A), we need to find P(A|B), the probability that someone with an IQ below 150 is labeled as having an IQ over 150. We can use Bayes' theorem to find this probability:

P(A|B) = P(B|A) * P(A) / P(B)

We know that P(B) = 1 - P(B'), the probability that someone with an IQ below 150 is not labeled as having an IQ over 150. Since everyone with an IQ over 150 is labeled as such, we have:

P(B) = 1 - P(A')

where P(A') is the probability that a random person has an IQ below 150 or, equivalently, 1 - P(A).

Plugging in the given values, we have:

P(A|B) = P(B|A) * P(A) / (1 - P(A))

P(A|B) = P(B|A) * 1/1100 / (1 - 1/1100)

P(A|B) = 0.0008 * 1/1100 / (1 - 1/1100)

P(A|B) ≈ 0.00073276

Therefore, the probability that the subject actually has an IQ below 150 given that they are labeled as having an IQ over 150 is approximately 0.00073276, or 0.07328% when rounded to five decimal places.
