Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway bet two entries, use the -score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. P7

The purpose and intent of the assignment is to help you better understand the sampling distribution of the mean. The class sampling exercise In class we conducted a sampling exercise. The population consisted of 25 elements. The possible values for the elements in the population ranged from 1 to 9 and were distributed as follows:   Value Frequency Proportion Percentage 1               1             0.04             4% 2               2             0.08             8% 3               3             0.12            12% 4               4             0.16            16% 5               5             0.2               20% 6               4             0.16             16% 7               3             0.12             12% 8               2             0.08               8% 9               1             0.04               4%   As in the class exercise, 10 elements are drawn replacing each element before the next is drawn. This was done 1000 times.  The data set is given in a separate…
