110 parts made from alloy 1 and 46 parts made from alloy 2 were subjected to stress tests. 16 parts from
alloy 1 and 14 parts from alloy 2 did not pass the test. Can we reject the hypothesis that the proportion of
nonpassing parts from alloy 1 is at least as large as the proportion of nonpassing parts from alloy 2 at a-0.01?
Assume independent samples
