Answer 1

To calculate the mean temperature, you need to add all the temperature readings together and then divide by the number of readings.

The temperatures are: 89, 85, 90, 87, 86, 91, 88, and 89.

1. First, add them together: \[ 89 + 85 + 90 + 87 + 86 + 91 + 88 + 89 = 86 + 91 + 88 + 89 + 89 + 90 + 87 + 85 = 721 \]

2. Count the number of temperature readings: There are 8 readings.

3. Now, divide the total by the number of readings to find the mean: \[ \text{Mean} = \frac{721}{8} = 90.125 \]

4. Rounding to one decimal place, the mean temperature is: \[ 90.1 \]

Thus, the mean temperature is 90.1 °F.
