Which of the following results in the null hypothesis $$ \mu = 15 $$ and alternative hypothesis $$ \mu < 15 $$? Select the correct answer below: An airline claims that the mean amount of time that a late flight is delayed is more than 15 minutes. An airline claims that the mean amount of time that a late flight is delayed is fewer than 15 minutes. An airline claims that the mean amount of time that a late flight is delayed is at most 15 minutes. An airline claims that the mean amount of time that a late flight is delayed is 15 minutes.

Step 1
The null hypothesis is given as $$ H_0: \mu = 15 $$. The alternative hypothesis is given as $$ H_1: \mu < 15 $$. Step 2: Interpret the alternative hypothesis. The alternative hypothesis $$ \mu < 15 $$ means that the mean amount of time a late flight is delayed is Show more…

A random sample of 48 flight departure delay times for America Airlines flights from New York (JFK) to Los Angeles was collected. Negative departure delay times correspond to flights that departed early. The mean of the 48 times is 10.5 minutes and the standard deviation is 30.8 minutes. Use a 0.01 significance level to test the claim that the mean departure delay time for all such flights is less than 12 minutes. H0: H1: p-value = Decision: Interpretation:

Triangle Airlines operating shuttle flights between New York and Boston, claims that the average flight time is 2 hours. A travel agency monitored 46 flight times and found that the mean time is 2 hours 8 minutes, and the standard deviation is 16 minutes. Can the travel agency justifies that the mean flight time is more than 2 hours. (a) State the null hypothesis and alternative hypothesis (b) Find the test statistic (c) If the type-I error α = 0.1, find the critical value(s) and shade the rejection region(s) (d) Base on the type-I error α and rejection region(s), given above, what is your conclusion? (e) Find the p-value
