Answer:
Given below
Range: 9
Mean: 16
Hope it helps:)
Step-by-step explanation:
The data is given in the question
Range-
All we need to do is find the difference between the largest data value in our set and the smallest data value. Stated succinctly we have the following formula:
Range = Maximum Value–Minimum Value
= 21- 12
= 9
Mean-
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. The formula is:
Sum of term/ number of terms = mean
= 17+21+14+17+12+15+16/7
= 112/7
= 16
