To find the mean temperature, we first need to sum all the temperature values and then divide by the number of values.
The temperatures (in °F) are: 89, 85, 90, 87, 86, 91, 88, and 89.
1. Calculate the sum:
\( 89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 720 \)
2. Count the number of temperature values:
There are 8 temperature values.
3. Calculate the mean:
\[
\text{Mean} = \frac{\text{Sum of temperatures}}{\text{Number of temperatures}} = \frac{720}{8} = 90
\]
So, the mean temperature is \( 90.0 \, °F \).
