Question:

John is planning to go on a cross country drive with his family. His Japanese minivan has been generally reliable but has 90,000 miles on it. So he wants to determine if the vehicle is mechanically sound for the arduous trip. He did a visual inspection of the vehicle and checked the oil and antifreeze levels and everything appears to look okay. The null and alternative hypotheses are given below. H0: minivan is mechanically sound Ha: minivan is not mechanically sound (a) What would a Type-I error be in this situation? (b) What would a type-II error be in this situation? (c) Which error is more consequential in this situation and why? (d) What impact would going to the mechanic have on the Type-I and Type-II errors and why?

Answer:

a. Type 1 error would be to reject null hypothesis and in reality, it is true. In this case, John does not accept minivan is mechanically sound but factually the minivan is mechanically sound b. John accepts minivan to be mechanically true but in fact it is not c. In this case, making a type II error is more consequential. Going on cross country drive with family on a minivan is not going to be a good experience. d. Going to mechanic will impact for good in case of Type II error. In case of Type I error, after inspection the mechanic will call out for false negative.
