The temperatures (°F) in a city on randomly selected days during the summer are 89,85,90,87,86,91,88 and 89. What is the mean temperature? Round to the nearest decimal point.

Answer 1

The mean temperature is calculated by adding up all the temperatures and dividing by the number of temperatures.

Mean temperature = (89 + 85 + 90 + 87 + 86 + 91 + 88 + 89) / 8
Mean temperature = 705 / 8
Mean temperature = 88.125

Therefore, the mean temperature is approximately 88.1°F.
