The data set shown below contains the number of hurricanes that occurred each year over a 14-year period. Some scientists claim that there has been an increase in the number of hurricanes as the years progressed. Complete parts (a) through (d). Year 1 3 4 7 8 9 10 11 12 13 140 1 #3 3 4 3 4 2 2 1 3 2 a) Create a histogram of these data. Choose the correct histogram below. O A. OB. OC. OD. 6- 6- Q 0- # of Hurricanes # of Hurricanes #of Hurricanes # of Hurricanes b) Describe the distribution. Is the distribution uniform, unimodal, or bimodal? O A. The distribution is unimodal. O B. The distribution is uniform. O C. The distribution is bimodal. Is the distribution symmetric or skewed? O A. The distribution is symmetric. O B. The distribution is skewed to the right. O C. The distribution is skewed to the left. Which of the following statements best describes the centre of the distribution? O A. The centre is best described by the median, 2.5 hurricanes. O B. The centre is best described by the mean, 3 hurricanes. OC. The centre is best described by the mean, 2.64 hurricanes. The range of the data is hurricanes. Describe any unusual features. O A. There is one year with an unusually large number of hurricanes. O B. There are no unusual features. OC. As the years progressed, the number of hurricanes increased. O D. There is one year with an unusually low number of hurricanes. Choose the correct graph below. O A. O B. OC. O D. Year Year Year Year d) Discuss the time series plot. Does this graph support the claim of these scientists? The time series plot support the claim that the number of hurricanes has as the years progressed. #of Hurricanes #of Hurricanes saupoun H 10
