Question

use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum = 8, maximum = 84, 7 classes the class width is 11. (type a whole number.) use the minimum as the first lower class limit, and then find the remaining lower class limits. the lower class limits are 8,19,30,41,52,63,74. (type a whole number. use a comma to separate answers as needed.) the upper class limits are. (type a whole number. use a comma to separate answers as needed.)

Explanation:

Step1: Recall upper - class limit rule

The upper - class limit of a class is one less than the lower - class limit of the next class (except for the last class). We know the lower - class limits are 8, 19, 30, 41, 52, 63, 74 and the class width is 11.

Step2: Calculate upper - class limits

For the first class, the lower - class limit is 8 and the class width is 11, so the upper - class limit is \(8 + 11-1=18\).
For the second class, lower - class limit is 19, so upper - class limit is \(19 + 11-1 = 29\).
For the third class, lower - class limit is 30, so upper - class limit is \(30+11 - 1=40\).
For the fourth class, lower - class limit is 41, so upper - class limit is \(41 + 11-1=51\).
For the fifth class, lower - class limit is 52, so upper - class limit is \(52+11 - 1 = 62\).
For the sixth class, lower - class limit is 63, so upper - class limit is \(63+11 - 1=73\).
For the seventh class, since the maximum value is 84, the upper - class limit is 84.

Answer:

18,29,40,51,62,73,84
