7. By the time you get to college, you must have heard it over and over again: "A picture is worth a thousand words." Now we have pictures and numbers discussed in Chapters 1 and 2, respectively. Why both? Well, although each one of them acts as a summary of a data set, it is a combination of the pictures and numbers that tells a big part of the story without having to look at the entire data set. Suppose that you ask a realtor for information on the prices of homes in two different but comparable suburbs. Let us call these Suburbs A and B. The realtor provides you with the following information that is obtained from a random sample of 40 houses in each suburb: All the information provided by the realtor is given in the following two tables and two histograms shown in Figures 3.16 and 3.17. Note that the second table gives the minimum and maximum prices of homes (in thousands of dollars) for each suburb along with the values of , median, and (in thousands of dollars).

Suburb A B

Average Price (in thousands of dollars) 221.9 220.03

Minimum Q1 Median Q3 Maximum

Suburb A 151.0 175.5 188.0 199.5 587.0

Suburb B 187.0 210.0 222.5 228.0 250.0

Decide which suburb you should buy the house in and tell me why?
