T 20. Hurricanes, again. A bimodal distribution usually dicates that there are actually two different behaviors present in the data. Investigating those two behaviors separately can produce important insights. Here are the data again, broken into two groups showing the number of hurricanes recorded annually before and after 1970. Create an appropriate visual display and write a few sentences comparing the two distributions. 1944-1969 1970-2000 3, 2, 1, 2, 4, 3, 7, 2, 3, 3, 2, 2, 1, 0, 1, 2, 3, 2, 1, 2, 2, 5, 2, 2, 4, 2, 2, 6, 0, 2, 5, 1, 2, 3, 1, 1, 1, 3, 0, 1, 3, 2, 3, 1, 0, 3 1, 2, 1, 1, 0, 5, 6, 1, 3, 5, 3T 26. Cities. Here's a histogram of the cost of living in 25 in- ternational cities. Costs are given in U.S. dollars. 15 10 # of Cities 5 60 100 140 180 Cost of Living ($) a) Write a few sentences describing this distribution. b) Does the most expensive city included here (Tokyo) appear to be an outlier? Explain.0.4081 T 28. Cities revisited. Here is a picture of the costs of living in 25 international cities rescaled to bars that are $12 -year age wide, rather than the $20 bins you saw in Exercise 26. that for of people represent 8 n aged 0 over 85. 6 # of Cities 4 her than 2 to show al exam. 84 108 132 156 Cost of Living ($) a) Describe what you see in this histogram. b) Now would you consider Tokyo, the most expensive city, to be an outlier? Defend your opinion. 29 7imous in the stem T 38. Drunk driving. Accidents involving drunk drivers ac- count for about 40% of all deaths on the nation's high- ways. The table tracks the number of alcohol-related fa- talities for 20 years.
