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.

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) What impact would going to an honest mechanic have on the Type-I and Type-II errors and why?
