For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300) = + x Is there a relationship between HwyMPG and displacement at the 0.05 level of significance?- Select your answer -YesNoItem 3 How much of the variation in the sample values of HwyMPG is is explained by this estimated regression equation?If required, round your answer to one decimal places. %
