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?
