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