Sagot :

Given:

The commute times were recorded and are shown in the form of data.

We have to construct a frequency table with the width= 0.2 and starting at 0.15

The frequency is given by the number of times the same value occur in the interval or the number of values that occur in that interval.

Therefore,

Class Interval Frequency

0.15- 0.35 4

0.35-0.55 7

0.55- 0. 75 8

0.75- 0.95 6

0.95- 1.15 5

1.15-1.35 0

1.35-1.55 2

Hence this is the required frequency table.
