1. For the population with mean of µ=60 and standard deviation of s=24. Find out the z score corresponding to each of following samples.

a. M=63 for sample of n=16 scores.

b. M=63 for sample of n=36 scores.

c. M=63 for sample of n=64 scores

2. A random sample is obtained from population with mean of m= 50 and standard deviation of s= 12.

a. For sample of n=4 scores, would a sample mean of M=55 be considered the extreme value or is it fairly typical sample mean?

b. For sample of n=36 scores, would sample mean of M=55 be considered an extreme value or is it fairly typical sample mean?
