hypotheses for hypothesis tests for slope correct answers H0: b1=b2=b3= 0
Ha: at least one b =/ 0
assumptions and conditions correct answers -linearity assumption
-independence assumption
-equal variance assumption
-normal population assumption
linearity assumption correct answers when the scatterplot is roughly straight
independence assumption
(randomization condition) correct answers the residual scatterplot had NO pattern
equal variance assumption
(equal spread condition) correct answers the residual plot spread is equal around the line y=0
normal population assumption correct answers the scatterplot has no outliers
how to preform a hypothesis test for slope correct answers look at the output (last table) for each
x-variable and decide to reject or fail to reject the x-variable (compare the p-value to the alpha
level)
standard error of the slope correct answers 2nd row, 2nd column, last table
standard error for the predicted value correct answers "standard error", first table
