The accompanying data table shows the engine ​size, x, in cubic
liters and rated miles per gallon​ (MPG), y, for a selection of
sedans. a. Using alpha α equals=​0.05, test for the significance of
the regression slope. b. Construct a​ 95% confidence interval for
the population slope. c. What conclusions about engine size and MPG
can be drawn from these​ results?
