Boomtowns. In 2006, Inc. magazine (www.inc.com)listed its choice of boomtowns in the United Stateslarger cities that are growing rapidly. Here is the maga-zines top 20, along with their job growth percentages: a) Make a suitable display of the growth rates.b) Summarize the typical growth rate among these citieswith a median and mean. Why do they differ?c) Given what you know about the distribution, whichof the measures in b) does the better job of summariz-ing the growth rates? Why?d) Summarize the spread of the growth rate distributionwith a standard deviation and with an IQR.e) Given what you know about the distribution, whichof the measures in d) does the better job of summariz-ing the growth rates? Why?f) Suppose we subtract from each of the precedinggrowth rates the predicted U.S. average growth rate of1.20%, so that we can look at how much these growthrates exceed the U.S. rate. How would this change thevalues of the summary statistics you calculatedabove? (Hint: You need not recompute any of thesummary statistics from scratch.)g) If we were to omit Las Vegas from the data, how wouldyou expect the mean, median, standard deviation, andIQR to change? Explain your expectations for each.h) Write a brief report about all of these growth rates.
