Return to question 3 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: points $143 $ 72 $139 161 $175 82 $129 $149 135 172 162 156 142 129 216 126 162 209 126 138 195 202 90 118 128 149 198 209 118 151 121 87 127 209 119 172 138 105 149 211 132 172 126 a. Find the smallest class interval. Use five classes. (Round your answer to 1 decimal place.) Answer is complete but not entirely correct. Smallest class 72.0 b. What would be a better class interval? Mc Graw HillExplanation / Answer
For the given data set 72 is the smallest number and 216 is the largest.
Hence range = 216 - 72 = 144
Smallest class interval = range / number of classes = 144/5 = 28.8
