Amelia read the thermostat in 9 different classrooms and recorded the following temperatures:

67°F, 67°F, 67°F, 66°F, 67°F, 69°F, 64°F, 64°F, 67°F

What was the range of the temperatures?

To determine the range of the temperatures recorded by Amelia in the 9 different classrooms, we need to follow these steps:

1. Identify and List the Temperatures:
The temperatures recorded are:
[tex]\[ 67^\circ \text{F}, 67^\circ \text{F}, 67^\circ \text{F}, 66^\circ \text{F}, 67^\circ \text{F}, 69^\circ \text{F}, 64^\circ \text{F}, 64^\circ \text{F}, 67^\circ \text{F} \][/tex]

2. Determine the Maximum Temperature:
The highest temperature among the recordings is:
[tex]\[ 69^\circ \text{F} \][/tex]

3. Determine the Minimum Temperature:
The lowest temperature among the recordings is:
[tex]\[ 64^\circ \text{F} \][/tex]

4. Calculate the Range:
The range of the temperatures is calculated by subtracting the minimum temperature from the maximum temperature:
[tex]\[ \text{Range} = \text{Maximum Temperature} - \text{Minimum Temperature} \][/tex]
[tex]\[ \text{Range} = 69^\circ \text{F} - 64^\circ \text{F} = 5^\circ \text{F} \][/tex]

Therefore, the range of the temperatures recorded by Amelia is:
[tex]\[ 5^\circ \text{F} \][/tex]
