an Investigator Wants $\mu$

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.
-Which of the following is an appropriate conclusion?

A) The results are statistically significant so the average total weight of all passengers appears to be greater than 185 pounds.
B) The results are statistically significant so the average total weight of all passengers appears to be less than 185 pounds.
C) The results are not statistically significant so there is not enough evidence to conclude the average total weight of all passengers is greater than 185 pounds.
D) None of the above.
