c) reject Ho at α .01 and 1 R Ho at α- d) F 1 R Ho at α-.05 and α-.01 e) none of these Question 16 0: Typically 10% o cars o fruit prepar du ingth current proces reduco oration afier 90 days. In arandom sample of 225 cans prepared with a new process, 12 show discoloration after 90 days. Perform an hypothesis test at α-.01 to de in the percentage of cans showing discoloration termine if the new process makes a difference 16. This hypothesis test is a involving a population a) 1TT, mean b) 1TT, proportion c) 2TT, mean d) 2TT, proportion e) none of these 17· The test statistic is: a) -2.33 b) .0098 c).0196 d) .0533 e) none of these 18. The critical z-scores are: a) ±1.645 b) ±1.96 c) ±2.33 d) ±2.58 e) none of these The p-value is: a) -2.33 b) .0098 c 0196 d) 0533 e none of these 19. Comparing the p-value to α, the test result is: a) reject Ho because the p-value is less than a b) FTR Ho because the p-value is less than a c) reject Ho because the p-value is greater than α d) FTR Ho because the p-value is greater than a e) none of these 20.
