The researcher is working with two distinct groups in the data set.

There are three different ways I can go to work in the morning. I want to see if there is a difference in the distributions of travel-times between the three different ways. The sample data is depicted below. I claim there is a difference in mean travel times between the three different routes. I cannot guarantee that the distributions of these travel times are Normal.     Travel Time in Minutes Interstate 22 22 21 23 22 21 Route 15 22 18 20 18     Back Roads 19 19 18 19 22   (a) Enter the rank values in the same order as in the original sample.   Interstate             Route 15         Back Roads           (b) Give the value of the test statistic:  (c) Test my claim at the 10% significance level.Enter the critical value: There is sufficient evidence to conclude that the population means are not equal.YesNo (d) Does your conclusion change at the 5% significance level?YesNo
