Answer 1

If we rearrange the given data set from lowest to highest, we have

`3,\:6,\:7,\:8,\:10,\:12,\:15,\:18`

The minimum is 3.

The first quartile is the average of 6 and 7, which is 6.5

The median is the average of 8 and 10 which is 9.

The third quartile is the average of 12 and 15 which is 13.5.

The maximum is 18.
