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 point)

Answer 1

To calculate the mean temperature, you need to sum all the temperature values and then divide by the number of values.

Let's add the temperatures:

\[ 89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 720 \]

Now, count the number of days (or temperature values):

There are 8 values.

Now, divide the total temperature by the number of values:

\[ \text{Mean} = \frac{720}{8} = 90 \]

So, the mean temperature, rounded to one decimal place, is:

90.0 °F
