Answer 1

• mean: 73.3
• median: 74
• range: 10

Explanation:

You want the mean, median, and range of the temperatures ...

{67, 70, 71, 72, 73, 74, 75, 75, 75, 77, 77}

Mean

The mean of the 11 temperatures is their sum, 806, divided by their number:

mean = 806/11 ≈ 73.3 . . . . degrees F

Median

The median of the 11 numbers is the 6th, when they are listed in order:

median = 74

Range

The range is the difference between the last number (77) and the first (67) when they are listed in order.

range = 77 -67 = 10

The mean, median, and range are 73.3, 74, and 10, respectively.
