Question

1 The heights of 9 students of a class are as follows (in cm):

155, 160, 145, 150, 147, 152, 144 148
a. Find the average height of the students in this class.

Answer 1

You only listed 8 kids...so the average of the 8 kids listed is 150.125!
The process:
You add all kids heights then divide by the amount of children. Like this-
155+160+145+150+147+152+144+148=1201
Then you divide by 8 to get 150.125
