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.
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.
