Construct the cumulative frequency distribution that corresponds to the given frequency distribution speed number of cars. Speed Number of cars
0-29 4
30-59 16
60-89 60
90-119 20

The cumulative frequency distribution that corresponds to the given frequency distribution is shown in the explanation part as well as in the attachment.

Step-by-step explanation:

A cumulative frequency distribution is the sum of the class and all classes below it in a frequency distribution.

The cumulative frequency distribution that corresponds to the given frequency distribution speed number of cars is shown below and better shown in the attachment below.
