Question
Transcribed Image Text:Westjet claims that it's avearage time to fly to Toronto from Thunder Bay is
121 minutes. A random sample of 29 flights from Thunder Bay to Toronto were
observed and yeilded a mean of 140 minutes. Assuming that o = 3.1 do we have
enough evidence to show that the mean flight is more than 121 minutes? Use
a = 0.1 and use our tables.
Select the correct null and alternative hypotheses:
OA. Ho: X= 140,HA: X < 140
OB. Ho: X= 140,H₁ : X ‡ 140
Ο C. Ho : μ = 121,HA : μ + 121
Ο D. Ho : μ = 121,HA : μ < 121
Ο E. Ho : μ = 121,HA : μ > 121
OF. Ho X = 140,H₁ : X > 140
OG. None of the above
Select the type of distribution to be used in this question:
OA. Z-distribution
B. t-distribution
OC. Chi-Square distribution
OD. None of the above
The rejection region for this test is:
OA. (-∞, -1.28)
OB. (1.96,∞)
OC. (1.645, ∞)
OD. (1.28, ∞)
OE. (-∞, -1.96)
OF. (-∞, -1.645)
OG. (-∞, -1.96) U (1.96,∞)
OH. (-∞, -1.28) U (1.28,00)
OI. (-∞, -1.645) U (1.645, ∞)
OJ. None of the above
Test statistic =
The conclusion for this test is:
OA. Fail to Reject Ho
OB. Reject Ho
OC. Fail to Reject HA
OD. Reject HA
OE. None of the above
