a. Organize the data into a frequency distribution, using seven classes and 15 as the lower limit of the first class. What class interval did you select?

b. Where do the data tend to cluster?

c. Describe the distribution.

d. Determine the relative frequency distribution.

Step-by-Step Solution:

Step 1 of 4</p>

a) We have to organise the given data into frequency distribution

Here the highest value is 84 from the given data

The interval is starting from 15

The no.of classes is 7

Then the class interval are 15-25, 25-35,........,75-85

Now the frequency distribution is

Class interval

Frequency

15-25

1

25-35

2

35-45

5

45-55

10

55-65

14

65-75

5

75-85

3

Total

40

Step 2 of 4</p>

b) we have to find where the data tend to cluster

Here from the frequency distribution the highest frequency corresponds to the class 55-65

Hence the data is clustered at 55-65
