Question

The below data shows the amount of time (in seconds) that animated Disney movies showed the use of tobacco and alcohol. Test the claim that the mean difference in time of tobacco use vs. alcohol use is equal to zero at the 0.05 significance level.

You may want to use a spreadsheet to help you solve this problem

Tobacco	Alcohol
64.1	66.9
35.6	47.4
29.3	48.4
46.5	47.2
65.7	92.9
62.7	90.1
63.4	84
48.9	51.7
43.7	66.7
49.5	55.2
63.4	76.8
58.1	64.7
41.7	61.8
35.6	45.4
41.4	47.2

Claim: Select an answer u ≥ 0 p ≥ 0 p ≠ 0 u > 0 p = 0 u = 0 u < 0 u ≤ 0 p < 0 p > 0 p ≤ 0 u ≠ 0  which corresponds to Select an answer H1: u < 0 H1: u > 0 H0: u ≤ 0 H0: u = 0 H0: u ≠ 0 H0: p ≥ 0 H1: u ≠ 0

Opposite: Select an answer p ≥ 0 p = 0 u = 0 p < 0 p > 0 u > 0 u ≠ 0 u < 0 u ≥ 0 p ≠ 0 p ≤ 0 u ≤ 0  which corresponds to Select an answer H0: p ≥ 0 H0: u = 0 H0: u ≤ 0 H1: u > 0 H1: u ≠ 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 -5.935 -5.755 -5.555 -5.055 -5.445  (to 3 decimals)

The Critical Value is: Select an answer ± 2.399 ± 2.498 ± 2.003 ± 2.145 ± 1.753  (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.
