Answer:
67°F
Step-by-step explanation:
The mean is another way to say average.
To find the average: you have to add up all of the temperatures, then divide by how many numbers (in this case, time slots) are there.
58°F + 60°F + 61°F + 67°F + 69°F + 73°F + 74°F + 74°F = 536°F
536°F ÷ 8 (total number of time slots) = 67°F
C might be the correct answer try it :)
