Question

You work for a parts manufacturing company and are tasked with exploring the wear lifetime of a certain bearing. You gather data on oil viscosity used and load. You see the regression output given below. What is the correct conclusion about the regression slopes based solely on the F-test? 1) All the regression slopes do not equal zero. 2) We do not have the dataset, therefore, we are unable to make a conclusion about the slopes. 3) We did not find significant evidence to conclude that at least one slope differs from zero. 4) At least one of the regression slopes does not equal zero. 5) All the regression slopes arc equal to zero.

Explanation / Answer

4)

Atleast one of the regression slopes does not equal to zero.

Why?

Because the pvalue of the regression equation is <.0001

Hence, the atleast one of the regression slopes does not equal to zero
