1. The problem asks us to calculate the mean temperature from the following values: 12°C, 11°C, 8°C, 13°C, and 16°C. 2. To find the mean, we sum all the temperatures and then divide by the total number of temperatures. 3. Calculate the sum: $$12 + 11 + 8 + 13 + 16 = 60$$ 4. Count the number of temperatures: 5 5. Calculate the mean: $$\text{mean} = \frac{60}{5} = 12$$ 6. Therefore, the mean temperature is 12°C.
