Answer:
Frequency distribution table is given in the image provided.
Explanation:
In this problem,
lowest data = 1
highest data = 37
Given that, class interval should be 7
Therefore, the lower limit of first class is 1 and upper limit of the same class is 1 + 7 = 8
i.e., first class => 1 - 8
second class => 8 - 15
If we encounter a data 8 in this case, we become confused about which class it belongs to. In order to avoid that, upper limit of every class is decreased by 1
i.e., first class => 1 - 7
second class => 8 - 14
and so on.
Also in this case, class width is calculated as
- difference of lower limits of 2 consecutive classes (here 8 - 1 = 7)
- difference of upper limits of 2 consecutive classes (here 14 - 7 = 7)
