Question

One of the flights was 350 miles and its residual was -

105.00. What was the fare for this flight?

Based on data taken from airline fares and distances

flown, it is determined that the equation of the least-

squares regression line is ý = 102.50 +0.65x, where

ý is the predicted fare and x is the distance, in miles.

O $102.50

O $435.00

O $225.00

O $330.00

Answer 1

(C) 225 Is correct.

Predicted cost - residual = answer

y= 102.50 + .65(35)

330 - 105 = 225

255

Answer 2

O $225.00

Explanation:

Given that

The one of the flight was 350 miles

And, its residual is 105

The regression line is y = 102.50 + 0.65x

where

y denotes the expected fare

And, x denotes the distance

We need to find out the fair of the flight

So,

y = 102.50 + 0.65 (350)

= 330.00

Now the fare is

= 330 - 105

= 225
