The low temperature during one week in January were 2°< -3°,-9°, -11°,-1°,-8°, and -9°. What was the median low temperature that week?

To find the median low temperature, we first need to arrange the temperatures in numerical order:

-11°, -9°, -9°, -8°, -3°, 2°

Since there is an even number of temperatures, we take the average of the two middle temperatures:

(-9° + -8°) / 2 = -8.5°

Therefore, the median low temperature for that week was -8.5°.
