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 percentage of the variability in humidity level explained by its relationship with temperature is 73.84%. Option B is the correct answer.

The percentage of the variability in humidity level explained by its relationship with temperature is given by the coefficient of determination, which is the square of the multiple correlation coefficient (R).

In this case, the R Square value is 0.7384, so the percentage of the variability in humidity level explained by its relationship with temperature is 73.84%. Therefore, the correct answer is: 73.84%. Option B is the correct answer.
