A chain of sport shops catering to beginning skiers, headquartered in Aspen, Colorado, plans to conduct a study of how much a beginning skier spends on his or her initial purchase of equipment and supplies. Based on these figures, it wants to explore the possibility of offering combinations, such as a pair of boots and a pair of skis, to induce customers to buy more. A sample of 44 cash register receipts revealed these initial purchases: $ 139 $ 82 $ 139 $ 161 $ 175 $ 82 $ 132 $ 149 $ 140 133 263 238 132 172 149 152 213 105 220 126 90 171 162 229 121 112 149 126 126 118 172 156 213 87 172 230 162 195 128 126 142 118 127 126 Click here for the Excel Data File a-1. Find the smallest class interval. Use five classes. (Round your answer to 1 decimal place.) 36.2 a-2. What would be a better class interval? $40 b.
