Use a 0.1 significance level to test the claim that the mean amount of delayed flight times between the two airlines is the same. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) H0: H1: Original Claim = df = Based on the hypotheses, find the following: Test Statistic = (Round to three decimal places.) Critical value(s) = ± (Round to three decimal places.)
Are the flight delay times the same for two different airlines?
For the following test, assume that the two samples are independent simple random samples selected from
In the table below are the statistics for the flight arrival delay times for flights traveling between city A and city B for two airlines; "Pink" and "Flamingo" airlines. Independent simple random samples of 22 flights from "Pink" and 22 "Flamingo" flights were selected.
Pink | Flamingo |
n1 = 22 | n2 = 22 |
xˉx̄1 = 47.1 min | xˉx̄2 = 52.1 min |
s1 = 1 min | s2 = 0.5 min |
