2.113 More hurricane damage Refer to the previous exercise about hurricane damage and the histogram shown there.

a. For this data, 93% of damages (i.e., all but the two most expensive) fall within one standard deviation of the mean. Why is this so different from the 68% the empirical rule suggests?

b. How would removing the costliest hurricane (Katrina in 2005, shown on the far right in the histogram) from the data set affect the (i) mean, (ii) median, (iii) standard deviation, (iv) IQR, and (v) 10th percentile?
