Check the model from Question 3 (two factors) for the normality of error terms using a plot. Is the distribution normal? Attach the plot

the question 3 mentioned in the text: Test for the effects of both A and B using two-way ANOVA. Report the p-values and state your conclusions from the test.

General context: Reliability of a machine (measured as time to failure) is thought to be influenced by two factors: A - average temperature of the contacting surfaces inside and B rate of lubricant usage. The machine was tested in different combinations of 4 fixed levels of each factor (assume it is possible). We are interested in analyzing the results.
