Question
For the z-score formula as it is used in a hypothesis test, answer the following questions.
(a) Explain what is measured by M - in the numerator. (chose A, B, C, D)
A) M - measures the difference between the sample mean and the standard error.
B) M - measures the difference between hypothesized population mean and the sample standard deviation.
C) M - measures the difference between the sample mean and the hypothesized population mean.
D) M - measures the difference between the sample mean and sample standard deviation.
(b) Explain what is measured by the standard error in the denominator. (chose A, B, C, D)
A) This measures the variance of the z-scores.
B) This measures how much difference, on average, is reasonable to expect between M and .
C) This measures how much difference, on average, is reasonable to expect between and .
D) This measures how much difference, on average, is reasonable to expect between M and .
Explanation / Answer
The correct answers are:
a) Correct answer is (C) M - measures the difference between the sample mean and the hypothesized population mean. This is because, M is the sample mean and mu is the hypothesized population mean.
b) Correct answer is (D) This measures how much difference, on average, is reasonable to expect between M and .
