O The number of observations is 5.
The median of the data set is 5.
O The mean of the data set is 8.
The range of the data set is 8.

Answer 1

the mean of the data set is 8. we know this because when the data set is all added together, (6+6+7+7+8+8+9+9+10+10) it equals 80. then, we divide this answer by the quantity of numbers in the data set (which is 10). this equals 8, and this is the mean.

Answer 2

The mean of the data is 8

Explanation:

6+6+7+7+8+8+9+9+10+10=80

80/10=8
