What is measured by the numerator of the z-score test statistic? a. The actual distance between M and µ b. Whether or not there is a significant difference between M and µ c. The position of the sample mean relative to the critical region d. The average distance between M and µ that would be expected if H0 was true

a. The actual distance between M and µ

Step-by-step explanation:

The z-score test is a statistical test for which the distribution of the test is normally distributed under null hypothesis. It is used to test the mean for a known standard deviation. The z score (z)  is the distance from the sample mean to the population mean in units of the standard error and is given by the equation:

, where μ is the mean, ο is the standard deviation, n is the number of samples in the population and is the standard error.

The numerator of the z score is the distance from the sample mean (μ) to the population mean (M).

after simplifying it i got: -36.25 as my answer. hope that !

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
