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?
Question 12 options:
We do not have the dataset, therefore, we are unable to make a conclusion about the slopes.
At least one of the regression slopes does not equal zero.
All the regression slopes do not equal zero.
We did not find significant evidence to conclude that at least one slope differs from zero.
All the regression slopes are equal to zero.PredictorcoefStevt - ratioConstant147 . 971 9723.53204181viscosity6 .2620.4713 . 21CO. COOLload0. 2980.047 . 430.
