Question

Refer to the previous exercise. A similar table relates cigarette use to alcohol use. The MINITAB output for the chi-squared test follows.
a. True or false: If we use cigarette use as the column variable instead of alcohol use, then we will get different values for the chi-squared statistic and the P-value shown in the table.
b. Explain what value you would get for the z statistic and P-value if you conducted a significance test of H0: p1 = p2 against Ha: p1 ≠ p2, where p1 is the population proportion of non cigarette users who have drunk alcohol and p2 is the population proportion of cigarette users who have drunk alcohol.
