Question

Analysis of the relationship between the fuel economy​ (mpg) and engine size​ (liters) for 35 models of cars produces the regression model ModifyingAbove mpg with caret equals 36.44 minus 3.829 times Engine size. If a car has a 5 liter​ engine, what does this model suggest the gas mileage would​ be?

Answer 1

Answer:

Gas mileage is 17.29

Explanation:

Given data:

The total number of the model is 35

The total size of the engine is 5 ltr

The regression model is given as

$36.44 - 3.829\times engine\ size$

From the information given in question we have

Regression equation is : model- mpg $= 36.44 - 3.829\times engine\ size$

Therefore for engine capacity of 5 liters;

Gas mileage $= 36.44 - 3.829\times 5  = 17.29$

Gas mileage is 17.29
