Question

Question 1 1 pts Use the following for questions 1, 2, and 3 The horsepower (HP) and miles per gallon (MPG) were obtained on 14 makes of automobiles. The output below is a linear regression analysis of these data. What is the meaning of the fact that the slope is negative? Regression Analysis: MPG versus HP 7-9-0-07 O There is an error in the data. As horsepower goes up, the miles per gallon go down. O The slope is not statistically significant Question2 1 pts Predict the MPG when HP 125. Question 3 1 pts What percent of the variability in MPG is explained by HP? 30.0% 2.716% 4.2%

Explanation / Answer

Hence the regression equation is,

Y = a + b x

Y =37.918 -0.03906 x

Here we have x =125

Y = 37.918 - 0.03906 * 125

= 33.0355
