Multiple Choice

Use the following information for questions:
An investigator wants to assess whether the mean $\mu$ = the average weight of passengers flying on small planes exceeds the FAA guideline of average total weight of 185 pounds (passenger weight including shoes, clothes, and carry-on) . Suppose that a random sample of 51 passengers showed an average total weight of 200 pounds with a sample standard deviation of 59.5 pounds. Assume that passenger total weights are normally distributed.
-What are the appropriate null and alternative hypotheses?

A) H₀: $\mu$ =185 and H_a: $\mu$ < 185
B) H₀: $\mu$ = 185 and H_a: $\mu$ >185.
C) H₀: $\mu$ = 185 and H_a: $\mu$ $\neq$ 185.
D) H₀: $\mu$ $\neq$ 185 and H_a: $\mu$ = 185.
