Claim: Select an answer u = 0 p 0 p 0 p > 0 u 0 u < 0 p = 0 p < 0 p 0 u > 0 u 0 u 0 which corresponds to Select an answer H0: u 0 H0: u 0 H1: u < 0 H1: u 0 H0: p 0 H1: u > 0 H0: u = 0 Opposite: Select an answer u 0 p 0 u 0 p < 0 u = 0 p > 0 u > 0 u < 0 p 0 p = 0 p 0 u 0 which corresponds to Select an answer H0: u 0 H0: u = 0 H1: u < 0 H1: u 0 H0: p 0 H1: u > 0 H0: u 0 The test is: Select an answer left-tailed two-tailed right-tailed The test statistic is: (to 3 decimals) The Critical Value is: (to 3 decimals) Based on this we: Select an answer Fail to reject the null hypothesis Reject the null hypothesis

Conclusion There Select an answer does does not appear to be enough evidence to support the claim that the mean difference in time of tobacco use vs. alcohol use is equal to zero.
