(g) Find a 95% confidence interval for the slope term of the model, B1.
Lower Bound =
67.571
(use three decimals in your answer)
Upper Bound =
76.314
(use three decimals in your answer)
(h) Choose the correct interpretation of the meaning of your confidence interval for B1, in the the context of the data.
A. There is a statistical relationship between the cost of flying a commercial flight using Boeing 737s and the number of passengers.
B. As the cost of flying a commercial flight using Boeing 737s increases by 1 unit, the number of passengers increases by an amount that is somewhere between the lower and upper bounds found in (g).
C. As the number of passengers increases by 1, the cost of flying a commercial flight using Boeing 737s increases by an amount that is somewhere between the lower and upper bounds found in (g).
D. As the cost of flying a commercial flight using Boeing 737s increases by 1 unit, the number of passengers will increase, on average, by an amount that is somewhere between the lower and upper bounds found in (g).
E. As the number of passengers increases by 1, the cost of flying a commercial flight using Boeing 737s will increase, on average, by an amount that is between the lower and upper bounds found in (g).
F. There is no statistical relationship between the cost of flying a commercial flight using Boeing 737s and the number of passengers.
(1) With 95% confidence, find the average cost of flying a commercial flight using Boeing 737s when the number of passengers is 70.
Lower Bound =
0.661
(use three decimals in your answer)
Upper Bound
