Suppose this professor happens to select Sample 83. (Hint: To see a particular sample, click the Observations button on the left-hand side of the DataView tool. The samples are numbered in the first column, and you can use the scroll bar on the right side to scroll to the sample you want.) Use the DataView tool to find the mean and the standard deviation for Sample 83. The mean for Sample 83 is0.803 . The standard deviation for Sample 83 is0.1130 . Using the distribution of sample means, calculate the z-score corresponding to the mean of Sample 83. The z-score corresponding to the mean of Sample 83 is .
