list to frequency table

Here is the list for heights in inches for all students who answered the question in our class survey, put in order from lowest to highest.


60, 60, 60, 61, 62, 62, 63, 63, 64, 65, 65, 66, 66, 66, 66, 66, 66, 66, 66, 68, 68, 69, 69, 69, 70, 70, 71, 71, 71, 72, 72, 74, 76, 77, 78

Only 35 subjects responded, so n = 35.

The frequency table reads as follows

_x____f(x)
60_____3
61_____1
62_____2
63_____2
64_____1
65_____2
66_____8
68_____2
69_____3
70_____2
71_____3
72_____2
74_____1
76_____1
77_____1
78_____1

You can check to see if you have missed any entries by finding the sum of the frequencies, which should be equal to n, which in this case is 35.
