A frequency distribution table has been started and is shown below. Enter the value that belongs where the question mark is located.
Interval Frequency Cumulative frequency
56-60
61-65 ?
66-70
71-75
Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! For each class count the number of values.
56-60 A
61-65 B
66-70 C
71-75 D
.
.
.
For cumulative frequency, sum the values going left to right.
56-60 A
61-65 A+B
66-70 A+B+C
71-75 A+B+C+D
So the value you want is the sum of A (number of values in 56-60 and B number of values between 61-65).
