In Bloomington, they randomly sampled 260 female voters, and 190 male voters. They collected data on the respondent's opinion on an environmental bond issue. We want to know whether there is good evidence that one's gender influences whether a person is for or against the bond issue. Use α = 0.05. For Bond Issue Against Bond Issue Total 52 260 17 190 69 450 Men Women Total a) What is the correct null hypothesis? O Ho: P₁ P2 P3 P4 O Ho: P₁ P2 = P3 P4 O Ho: Gender and Bond Issue Attitudes are Independent.

You are driving home one night and must decide if you have enough gas to get home or not. Use the hypotheses below to answer the questions. Ho: My vehicle has enough gas to get home.Ha: My vehicle does not have enough gas to get home. A. A type I error occurs if I conclude (believe) my vehicle does/does not (circle the correct choice) have enough gas to get home, but in fact, my vehicle does / does not (circle the correct choice)have enough gas to get home. B. List one possible consequence that could happen if you made a type I error. C. A type II error occurs if I conclude (believe) my vehicle does / does not (circle the correct choice ) have enough gas to get home, but in fact, my vehicle does / does not (circle the correct choice) have enough gas to get home. D. List one possible consequence that could happen if you made a type Il error. E. Based on the seriousness of the consequences of these two errors, we should set a / B to be less than a /B.
