Question

ten cyclists were each asked the distance in miles they biked last week. their responses are given below. complete the grouped frequency - distribution for the data. in the distribution, the frequency of a class is the number of distances in that class. (note that we are using a class width of 5.) distance in miles: 9 12 17 10 15 2 13 12 2 7

Explanation:

Step1: Count for 1 - 5

The data values in the range 1 - 5 are 2, 2. So the frequency is 2.

Step2: Count for 6 - 10

The data values in the range 6 - 10 are 9, 10, 7. So the frequency is 3.

Step3: Count for 11 - 15

The data values in the range 11 - 15 are 12, 15, 13, 12. So the frequency is 4.

Step4: Count for 16 - 20

The data value in the range 16 - 20 is 17. So the frequency is 1.

Answer:

1 to 5: 2
6 to 10: 3
11 to 15: 4
16 to 20: 1
