The climatologist you were consulting with last week has moved on to look at the effects of hurricanes. The hurricanes dataset includes the estimated damage caused by each hurricane in millions of 2013 dollars (damage_norm). The climatologist would like to know whether the average damage is over $1 billion (i.e., a value of 1000 for damage_norm). The climatologist decides to use a � = .05 significance level with a two-sided test. a. Examine a histogram of the damage amounts and comment on its characteristics. b. Why might it be helpful to use the median damage, rather than the mean damage caused by the hurricanes? From the perspective of statistical inference, what might be the drawback of using the median, instead of the mean? c. What is the best guess for the median damage caused by hurricanes? d. What test statistic will you use for a test of the median? (Explain how you found your answer.) e. Find the p-value for the test of the median. Explain what this p-value represents in the context of this research scenario. f. What conclusion should the climatologist draw about hurricane damage? g. The climatologist doesn’t understand why his best guess for the damage of hurricanes seems to conflict with the conclusion you said he should draw from the statistical test. How would you explain this apparent conflict to him?

For each R command below, please write the result you would get when you execute the command. (Of course, feel free to execute the command in R to see what it produces. However, to really benefit from this exercise, I recommend that you try to guess what the command will produce before you actually execute the command in R.): a) x = c(1,2,3,4,5) x b) y = seq(from=35, to=55, by=5) y c) z = seq(from=0, by=2, length=4) z d) x * y e) x * z f) a = x[x
