Eleven students were asked to measure their pulses for 30 seconds and multiply by two to get their one-minute pulse rates. The results were:

32, 60, 62, 66, 70, 72, 74, 74, 78, 80, 84

a) Create a five-number summary for these pulse rates and sketch a box-plot.

b) Find the sample mean by the formula x=xnx=xnand sample standard deviation with the formulass=(xx)2n1s=(xx)2n1. Make sure you create a similar table when calculating the standard deviation.

c) The pulse rate of 32 is an outlier because the student forgot to multiply by two. Correct the outlier and redo part a.

d) For each of the following statistics, specify whether it would increase, decrease or remain approximately the same after the outlier is corrected:

The mean

The median

The standard deviation-
