For a population with a mean of 40 and a standard deviation of 8 find the z-score corresponding to each of the following samples.
x = 34 for a sample of n = 1 score:
m = 34 for a sample of n = 4
m = 34 for a sample of n = 16

a) -0.75

b) -1.5

c) -3

Step-by-step explanation:

Population Mean = u = 40

Standard deviation = s = 8

We are given a value to convert it into z-score with different sample sizes.

For a given sample size "n", the formula to calculate the z-score is:

For x = 34 and n=1, we get:

For x = 34 and n = 4, we get:

For x = 34 and n = 16, we get:

f

step-by-step explanation:

f

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
