Question

A task force to encourage car pooling did a study of one-way commuting distances (in miles) of workers in the downtown Dallas area. A random sample of 60 of these workers was taken. The commuting distances of the workers in the sample are given in the following grouped frequency distribution: Class limit (distance in miles) Frequency 1 - 10 18 11 - 20 24 21 - 30 10 31 - 40 4 41 - 50 4 For this grouped frequency distribution, the modal class is A. 11 - 20 B. 21 - 30 C. 1 - 10 D. 41 - 50

Answer 1

Answer:

The modal class is 1 - 10

Step-by-step explanation:

Given

See attachment for frequency distribution table

Required

Determine the modal class

To determine the modal class, we simply look for the class with the highest frequency.

In the given frequency distribution table, class 1 - 10 has the highest frequency of 21.

Hence, the modal class is 1 - 10
