Home Pros sells supplies to €œdo-it-yourselfers.€ One of the things the company prides itself on is fast service. It uses a number system and takes customers in the order they arrive at the store. Recently, the assistant manager tracked the time customers spent in the store from the time they took a number until they left. A sample of 16 customers was selected and the following data (measured in minutes) were recorded:

a. Compute the mean, median, mode, range, interquartile range, and standard deviation.
b. Develop a box and whisker plot for these data.
