Answer with explanation:
The variate in Data set are:
21, 37, 56, 87, 32, 45, 77, 71, 65, 67, 21, 34
Arranging the variate in Ascending order
21, 21, 32,34,37,45,56,65,67,71,77,87
Now, We have to make five Intervals in which we have to place this data
Class Interval Variate of Data set Frequency
20-35 21,21,32,34 ||||=4
35-50 37,45,56, |||=3
50-65 0 0
65-80 65,67,71,77 ||||=4
80-95 87 |=1
Now drawing the Histogram for the given variate by making five intervals
