. What are the hypotheses to determine whether a population mean exceeds 942? ← . Following these overall patterns, what do you think the hypotheses would be to determine if a opulation proportion is different than 0.25? . Following these overall patterns, what do you think the hypotheses would be to determine whether a opulation variance is more than 337.4? . A company instituted a sales incentive program to encourage more effort by its reps during sales calls. Prior to the incentive program, the average (mean) sale made per call was $500. If the sales incentive rogram works, presumably they should see an increase in the average sales made per call, all other hings equal. What hypotheses could the company use to test whether their sales incentive program is ssociated with an increase in population mean sales per call? A fish hatchery raises fish that weigh 7 pounds on average after 32 weeks. The hatchery has built a ew pond facility, which is troubled. The hatchery suspects that the new pond facility is not working to pec, and therefore the fish are not growing as fast as usual. What hypotheses should the company use o see if the population mean weight of the fishes at the new pond facility are smaller (i.e. lighter) than verage, compared to the rest of the fish the hatchery raises? . A company fills bags of chocolates to a weight of 64 grams each. If all the bags weigh 64 grams, as lanned, then the population of bags should average 64 grams. What hypotheses can the company use o test whether the population of bags weigh 64g on average or not? ||| O r
