11. The first histogram below shows the distribution of the yearly incomes of 40 patrons at a college coffee shop. Suppose two more patrons are considered: one making $225000 and the other $250000. The second histogram shows the new income distribution. Summary statistics are also provided. 60000 62500 65000 67500 (1) 70000 (1) 40 n Min. 60680 1st Qu. 63620 Median 65240 Mean 65090 3rd Qu. 66160 (2) 42 60680 63710 65350 73300 66540 Max. 69890 250000 SD 2122 37321 60000 110000 160000 210000 260000 (2) a. Would the mean or the median best represent what we might think of as a typical income for the 42 patrons at this coffee shop? What does this say about the robustness of the two measures? b. Would the standard deviation or the IQR best represent the amount of variability in the incomes of the 42 patrons at this coffee shop? What does this say about the robustness of the two measures?
