3. Next, calculate the value of the z statistic for each of the 200 samples. We can calculate z in this example because we know that the samples were selected from a population for which s 5 10. Use the calculator function of Minitab to compute z 5 x 2 m ss/Ïnd 5

x 2 100 s10/Ï5d as follows:

Calc → Calculator In the “Store results in” box, enter c10 In the “Expression box” type in the following: (c7-100)/(10/sqrt(5))

Click on OK You should now see the z values for the 200 samples in c11. Name c11 “z.”
