The factory owner claimed that their bottled fruit juice has the capacity of less than an average of 280 ml. To test the claim, a group of consumers gets a sample of 80 bottles of the fruit juice, calculates the capacity, and then finds the mean capacity to be 265ml. The standard deviation is 8ml. Use a = 0.05 level of significance to test the claim. A. 25 -1.645 C. z 2 1.645 B. IS -1.28 D. z 2 2.33 15. Based on the given problem in no. 14, which is the appropriate rejection region? A. C. B. D
