Claim: Select an answer p > 0 u ? 0 u ? 0 p < 0 u > 0 p? 0 p ? 0 p ? 0 u < 0 p = 0 u ? 0 u = 0
which corresponds to Select an answer H1: u > 0 H0: u ? 0 H1:u < 0 H0: u ? 0 H1: u ? 0 H0: u = 0 H0: p ? 0
Opposite: Select an answer u < 0 p > 0 p ? 0 u = 0 p ? 0 u? 0 u ? 0 p ? 0 u > 0 p = 0 p < 0 u ? 0
which corresponds to Select an answer H1: u < 0 H0: u ? 0 H1:u ? 0 H0: u ? 0 H0: p ? 0 H0: u = 0 H1: u > 0
The test is: Select an answer / left-tailed / two-tailed /right-tailed
The test statistic is: Select an answer / -6.969 / -7.119 /-6.289 / -6.729 / -6.609 (to 3 decimals)
The Critical Value is: Select an answer / ± 1.711 / ± 1.47 / ±1.316 / ± 1.36 / ± 1.867 (to 3 decimals)
Based on this we: Select an answer / Fail to reject the nullhypothesis/ Reject the null hypothesis
Conclusion There Select an answer (does / not does ) appear to be enough evidence tosupport the claim that the mean difference in time of tobacco usevs. alcohol use is equal to zero.
