Question: An airline designs a study to evaluate fuel usage by a certain type of aircraft. From a random sample of 50 flights, the flight length

An airline designs a study to evaluate fuel usage by a certain type of aircraft. From a random sample of 50 flights, the flight length in hundreds of miles and the fuel usage in gallons are recorded.

a. Plot fuel usage versus and mileage. Does the plot display a linear relationship between fuel usage and length of flight?
b. Obtain a regression equation relating fuel usage to length of the flight.
c. What is the interpretation of Î²1 in this situation?
d. Is there a sensible interpretation of Î²0 in this situation?
e. Compute the correlation coefficient, ryx, and the coefficient of determination. Interpret these values.
