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).

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
