(a) Make a box-and-whisker plot of the data. Find the interquartile range.

(c) If you have a statistical calculator or computer, use it to find the actual sample mean and sample standard deviation. Otherwise, use the values Σx = 2769 anΣx2
 = 132,179to compute the sample mean and samplestandard deviation.
