Question

To model the relationship between temperature (X, in degrees) and humidity level (Y, as percentage), a meteorologist collected data from 10 days. The Excel output is shown below (some cells are intentionally blank).

Answer 1

The predicted humidity level for a day when temperature is expected to be 50 degrees is 85.93%. Option D is the correct answer.

To predict the humidity level for a day when temperature is expected to be 50 degrees, we can use the estimated regression equation:

Humidity level = 15.784 + 1.282 * Temperature

Plugging in the temperature of 50 degrees, we get:

Humidity level = 15.784 + 1.282 * 50 = 85.93

Therefore, the predicted humidity level for a day when temperature is expected to be 50 degrees is 85.93%. Option D is the correct answer.
