Question

(a) complete the grouped frequency distribution for the data. (note that the class width is 5.)
number of miles frequency
1 to 5 4
6 to 10 6
11 to 15 2
16 to 20 2
(b) construct a

Explanation:

Step1: Identify the task

We need to complete the grouped - frequency distribution. Since no upper - bound class is given, we assume we need to find the total frequency.

Step2: Calculate the total frequency

Add up the given frequencies: $4 + 6+2 + 2$.
$4+6+2 + 2=14$

Answer:

The total frequency of the data set is 14.
