Answer:

The correct answer is letter "A": Hybrid cars get better gas mileage than traditional cars.

Explanation:

One-Tailed Tests are statistical studies conducted to show that a given sample has higher or worse features than the total population. The two outcomes cannot happen. Only one will be the result of the test. The researcher, in such a case, conducts the study in one direction and does not consider the other possible outcome.

Then, <em>the research on hybrid cars attempts to prove they are better in gas mileage compared to regular vehicles. Therefore, the researcher is using the one-tailed test approach.</em>

The cost of underestimating the demand is considered a revenue loss that arises due to cancellation of flight costing $134. Hence, cost of underetimating the demand is $C_u=\$134$ .

The cost of overestimating the demand is known as rewards. For example, free round trip ticket worth $263. Hence, the cost of overestimating the demand is $C_o=\$263$ .

$\frac{C_u}{C_u+C_o} = \frac{134}{134+263} \\ \\ = \frac{134}{397} =0.3375$

The z-score that yields a p-value of 0.3375 is -0.4193.

Thus, super discount airlines should overbook the flight by 35 + (-0.4193 x 24) = 35 - 10.0632 = 24.9368 = 25 seats.

Therefore, super discount airlines should overbook the flight by 25 seats.
