Question

a professor had students keep track of their social interactions for a week. the number of social interactions over the week is shown in the following grouped frequency distribution. what is the class width? the class width is (type a whole number.) number of social interactions frequencies 35-43 6 44-52 12 53-61 14 62-70 12 71-79 11 80-88 10 89-97 6 98-106 5 107-115 0 116-124 4

Explanation:

Step1: Recall class width formula

Class width = Upper bound - Lower bound of a class.

Step2: Calculate using first class

First class: 35-43. Width = 43 - 35 = 9.

Step3: Verify with another class

Second class: 44-52. Width = 52 - 44 = 9. Consistent.

Answer:

9
