106 parts made from alloy 1 and 47 parts made from alloy 2 were subjected to stress tests. 17 parts from alloy 1 14 and 15 parts from alloy 2 did not pass the test. Can we reject the hypothesis that the proportion of nonpassing IS parts from alloy 1 is at least as large as the proportion of nonpassing parts from alloy 2 at a=0.025? Assume 16 independent samples. 17 18 19 20 21 Question 1 For the hypothesis stated above (in terms of alloy1 - alloy2): 22 23 Part A What is the decision rule? Fill in only one of the following statements. 24 25 If the hypothesis is one tailed: 26 Reject Ho if 29 If the hypothesis is two tailed: 30 Reject Ho if 32 33 34 Part B What is the test statistic? 35 36 37 38 Question 2 Find the 80% confidence interval (in terms of alloy2 - alloy1). 39 40 Left Endpoint = Right Endpoint = 41
