Answer 1

Answer:

Mean = 8.23

Median = 8

Mode = 7

Step-by-step explanation:

Let us arrange the data accordingly:

7 7 7 7 7 7 8 8 8 9 10 11 11

MEAN

The mean is obtained by adding them up and dividing by the 13:

(7 + 7 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 10 + 11 + 11) / 13

= (42 + 24 + 9 + 10 + 22) / 13

= 107 / 13 = 8.23

MEDIAN

This is the number in the middle. There are 13 numbers and so the median will be the 7th.

The median is 8.

MODE

The mode is the number that appears the most.

The mode is 7
