In the hope of attracting more riders, a city transit company plans to have express bus service from a suburban terminal to the downtown business district. These buses should save travel time. The city decides to perform a study of the effect of four different plans (such as a special bus lane and traffic signal progression) on the travel time for the buses. Travel times (in minutes) are measured for several weekdays during a morning rush-hour trip while each plan is in effect. The results are recorded in the following table.

Plan
1	2	3	4
27	25	34	30
25	28	29	33
29	30	32	31
26	27	31
	24	36

a What type of experimental design was employed?

b Is there evidence of a difference in the mean travel times for the four plans? Use α = 0.01.

c Form a 95% confidence interval for the difference between plan 1 (express lane) and plan 3 (a control: no special travel arrangements).
