b.Explain what you have done to a person who has never had a course in statistics. In order to calculate the mean or average for the governors and CEO’s, I added together all the figures and divided that sum by 4 since there are 4 numbers. Calculate the standard deviation by getting the average of the average (mean) of the numbers. So the average of 43 for the governors is 6.831300511 and the average for the CEO’s is 12.64911064 c.Note the ways in which the means and standard deviations differ, and speculate on the possible meaning of these differences, presuming that they are representative of U.S. governors and large corporations’ CEOs in general. From these results, it appears that CEO’s have larger desks than the...
