Wait-Times (Raw Data, Software Required):

There are three registers at the local grocery store. I suspect the mean wait-times for the registers are different. The sample data is depicted below. It gives the wait-times in minutes.

Register 1Register 2Register 32.01.82.12.02.02.11.12.21.82.02.61.51.01.81.42.02.11.41.02.22.01.61.71.8

The Test:Complete the steps in testing the claim that there is a difference in mean wait-times between the registers.

(a) What is the null hypothesis for this test?

H0:?2>?3>?1.

H0:?1=?2=?3.

H0:At least one of the population means is different from the others.

H0:?1??2??3.

(b) What is the alternate hypothesis for this test?

H1:?1=?2=?3.

H1:?2>?3>?1.

H1:At least one of the population means is different from the others.

H1:?1??2??3.

(c) Use software to get the P-value of the test statistic (F).Round to 4 decimal places unless your software automatically rounds to 3 decimal places.

P-value =

(d) What is the conclusion regarding the null hypothesis at the0.10significance level?

rejectH0

fail to rejectH0

(e) Choose the appropriate concluding statement.

We have proven that all of the mean wait-times are the same.

There is sufficient evidence to conclude that the mean wait-times are different.

There is not enough evidence to conclude that the mean wait-times are different.

(f) Does your conclusion change at the0.05significance level?

Yes

No
