°F
To find the mean temperature, we need to add up all the temperatures and then divide the sum by the number of temperatures.
Adding up all the temperatures:
89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 705
Dividing the sum by the number of temperatures:
705 / 8 = 88.125
Rounded to one decimal place:
88.1
The mean temperature is 88.1 °F.
