The temperatures (in °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 your answer to one decimal place.

1 answer

The mean temperature can be calculated by adding all the temperatures together and then dividing by the number of temperatures.

Mean temperature = (89 + 85 + 90 + 87 + 86 + 91 + 88 + 89) / 8
Mean temperature = 705 / 8
Mean temperature = 88.1°F

Therefore, the mean temperature in the city during the summer is 88.1°F.
