Use the Descriptive Statistics selection from the Analysis ToolPak to find the mean and standard deviation for the student GPAs in Figure 5.6. Compute how many GPAs are within one standard deviation of the mean. Compute this by adding the standard deviation to the mean and then sub- tracting the standard deviation from the mean. How many GPAs lie within the range of the two numbers? What percentage of the GPAs lie within one standard deviation of the mean? 2.
