Asample is obtained from a population with m = 100 and s = 20. which of the following samples would produce the most extreme z-score? a sample of n = 25 scores with m = 102 a sample of n = 100 scores with m = 102 a sample of n = 25 scores with m = 104 a sample of n = 100 scores with m = 104

A sample of n = 100 scores with M = 104 gives the most extreme z-score.

Step-by-step explanation:

The difference between sample mean and population mean is (Standard Error of the Mean) can be written by the formula

SE=(M-m)= where M is the sample mean, m is the population mean, z is the z-score, s is the population standard deviation, n is the size of the sample. From this we can find out that

z=(M-m)×

       z=(102-100)× =0.5

        z=(102-100)× =1

        z=(104-100)× =1

        z=(104-100)× =2
