An investigator wants to prove that = 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. What are the appropriate null and alternative hypotheses? A. H0: b. H0: c. H0: d. H0: =185 and Ha: = 185 and Ha: = 185 and Ha: 185 and Ha: < 185 >;185. 16. An investigator wants to prove that = 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. What is the value of the test statistic?
