This insight enables you to quickly estimate the standarddeviation of a data set by finding the maximum and minimum data values, using them tocompute the range, and then dividing this value by 4.1.Each of the following 5 data sets has a mean close to 100, and a standard deviation in the20s. Assume that each of these are sample data sets.For each of the 5 data sets given below,use the Excel function “=stdev.s” (or technology) to find the actual sample standard deviation(10 points), compute the estimate given by the Range Rule of Thumb (RROT) Estimate (10points), and compute the percentage error of the estimate (10 points). The formula for the
