B 1 0. Test whether the slope of the regression line in Example 1. The slope of the regression line is equal to zero. β 0 ie. Hypothesis test for testing that one slope parameter is 0. First state the hypothesis H0.

B 1 0.

B 1 0. Hypothesis test for testing that all of the slope parameters are 0. To conduct a hypothesis test for a regression slope we follow the standard five steps for any hypothesis test. If the hypothesis is rejected a test. If it is assumed that these e values are normally distributed a test of the hypothesis that β1 β2 versus the alternative that they are unequal can be constructed. If the relationship between home size and electric bill is significant the slope will not equal zero.
