Question

c. Provide an interpretation for the value of the slope.

Because the slope is

?

A. positive

B. negative

?, it can be concluded that a one

?

A. cubic liter

B. mile per gallon

increase in

?

A. miles per gallon

B. engine size

will

?

A. decrease

B. increase

the

?

A. engine size

B. miles per gallon

by an average of

_____________

?

A. cubic liters.

B. miles per gallon.

?(Round to three decimal places as? needed.)

Suppose an environmental agency would like to investigate the relationship between the engine size of sedans and the miles per gallon (MPG) they get. The accompanying table shows the engine size in cubic liters and rated miles per gallon for a selection of sedans. Use this information to complete parts a through f ?Click to view the table showing engine size and MPG for 9 car models. OA. B. ? D. 32 32 19 32 1.9 19 32 1.9

Explanation / Answer

From given information,

Slope = b = - 4.383 and y_ intercept = 36.711

So regression equation will be, y = 36.711 - 4.383*x

Where , y = Mile per gallon ( dependent variable )

x = cubic liter ( independent variable )

c ) Interpretation of slop -

Because the slop is negative , it can be concluded that a one cubic liter increase in engine size will decrease the miles per gallon by an average of - 4.383
