Question

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 the 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 Organize the data into a frequency distribution using a lower limit of $80.

Step 1

To find the range, subtract the smallest value from the largest value in the dataset. The smallest value is $82, and the largest value is $263. So, the range is $263 - $82 = $181. Step 2: Decide on the number of classes for the frequency distribution. A common Show more…

00:01 Okay so i see that you need help with this question and so um it wants you it says a chain of sports shops catering to beginner skiers headquartered in aspen colorado plans to conduct a study of how much beginner skier spends on his or her initial purchase of equipment and supplies based on these figures she 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.

00:29 A sample of 44 cash register receipts revealed these initial purchases.

00:34 All right, so find the smallest class interval.

00:36 Use five classes.

00:37 So first of all, the smallest number i'm going to say right now is is 82.

00:43 And the largest number, i have 230 here.

00:48 And then we have 262.

00:55 And so 262 minus 82, that's 180.

01:03 Divide that by 5, and that's 36.

01:09 So smallest class interval would be 36.

01:16 Oh, oh, i'm sorry.

01:19 So that would be 36.

01:21 Ok.

01:22 And then going from you would start at 82, 82 plus 36.

01:33 And you would go to 117 and that would bring you to your five classes.

01:41 What would be a better class interval? of all.

01:43 So i think that going from 82 to 262 would be 50 to 99 and then 100 to 149.

01:58 I just think it's easier to place the numbers.

02:02 So let's actually, we'll do it over here.

02:06 So class, so we have 50 to 99, 100 to 150, i'm sorry, to 149, 150 to 199, 200 to 250...
