(a) Use class intervals of $0 to <$3, $3 to <$6, $6 to <$9, etc., to create a relative frequency distribution for these data. (Round your answers for relative frequency to four decimal places.) Class Interval Frequency $0 <$3 $3 <$6 $6 <$9 $9 <$12 $12- <$15 $15 <$18 $18 - <$21 TOTAL (b) Construct a histogram.

The distribution is positively skewed. This is a unimodal distribution with a peak at the 0-3 class. The distribution is positively skewed. This is a bimodal distribution with peaks at the 12-15 and 18-21 classes. The distribution is negatively skewed. O This is a unimodal distribution with a peak at the 9-12 class. The distribution is reasonably symmetric. Cost Cost (c) Using the relative frequency distribution or the histogram, estimate the proportion of the states that have a minimum monthly cost of less than $12.00 a month. (Round your answer to one decimal place.) %

Medicare's new medical plans offer a wide range of variations and choices for seniors when picking a drug plan. The monthly cost for a stand-alone drug plan varies from plan to plan and from state to state. The accompanying table gives the premium for the plan with the lowest cost for each state. State Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware District of Columbia Florida Georgia Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico New York North Carolina North Dakota Ohio Oklahoma Oregon Pennsylvania Rhode Island South Carolina South Dakota Tennessee Texas Utah Vermont Virginia Washington West Virginia Wisconsin Wyoming Cost per Month (dollars) 4.61 20.18 10.69 9.30 9.43 11.06 7.94 7.41 1.87 14.17 1.87 1.87 10.10 15.78 7.08 6.10 3.08 18.35 15.81 19.17 8.11 6.30 7.21 13.72 6.27 10.48 8.37 10.53 14.09 13.75 1.87 17.57 8.83 16.84 10.13 4.51 10.14 7.46 12.26 1.87 7.56 8.58 14.20 7.15 11.26 1.87 13.37 11.30 1.87 14.72 11.43
