As regional manager, you have been observing the perfor- mance of one of your sales reps as she makes her sales calls over a three-day observation period. The time, in min- utes, that she spent with each of 10 clients is shown below: 106, 100, 100, 97, 89, 95, 93, 181, 99, 100 Treat the data as a sample.

a. Compute the rep's mean time per client.

b. Determine and interpret the median and the mode (if any).

c. Compute and interpret the range, MAD, variance and standard deviation. (Note: The sum of the squared deviations is 6442.)
