A small business owner has two fast food restaurants. The owner wants to determine if there is any difference in the variability of service times at the drive-thru window of each restaurant.
A sample of size n = 9 is taken from each restaurant's drive-thru window. To perform a hypothesis test using the 0.05 level of significance the critical value is:A) 3.438
B) 3.197
C) 4.026
D) 4.433
Question 2
Two airlines are being compared with respect to the time it takes them to turn a plane around from the time it lands until it takes off again.
The study is interested in determining whether there is a difference in the variability between the two airlines. They wish to conduct the hypothesis test using an alpha = 0.02. If random samples of 20 flights are selected from each airline, what is the appropriate F critical value?A) 3.027
B) 2.938
C) 2.168
D) 2.124
