Question 1023801:  A researcher measured the heights of forty high school students. The measurements are recorded below. 
Heights (in inches):
 
58  59  59  60  60  61  61  61  61  62  62  62  62  62  62  63  63  64  65  66 67  67  68  68  68  68  69  69  70  70  70  71  71  71  71  71  72  73  74  75 
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

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).
