The asking prices (in thousands of dollars) of some four-bedroom homes in Akron, Ohio, are described by the dotplot in Fig. 51.

a. A buyer can afford to pay up to $150 thousand. Assuming sellers will not lower their asking prices, what proportion of the homes can the buyer afford?
b. What proportion of the homes have asking prices between $250 thousand and $350 thousand?
c. If there were two outliers, estimate their values.
d. It turns out that the two homes with asking prices you identified in part (c) also have square footages that are outliers. Why does this make sense?
e. The data set does not include the asking prices of foreclosed homes. If the population were all types of four-bedroom homes, what type of bias in sampling occurred? If the asking prices of foreclosed homes had been included, how would the dotplot most likely be different?
