For Ho : β =. 1. 0 the -value is 0.0. The p-value is the probability of obtaining a test statistic that is at least as extreme as the calculated value if there is actually no difference (null hypothesis is true). With a p-value of 0.0, there is very strong evidence to suggest that the simple linear regression model is useful for BAC.

There should be no apparent pattern in the residual plot. However, if there is fanning in (or fanning out), then the equality of variance part of this assumption may be violated.
