7.42 When is 52 weeks not equal to a year? Refer to the previous exercise. The researchers also had 60 marketing students read an announcement about a construction project. The expected duration was either 1 year or 52 weeks. Each student was then asked to state the earliest and latest completion dates. Group 52 weeks 1 year n 30 30 x 84.1 139.6 S 55.8 73.1 Test that the average interval is the same for the two groups, using the a = 0.05 significance level. Report the test statistic and P-value and give a short summary of your conclusion. (Software gives k = 54.2.) (This k is the degree of freedom for the t distribution) 7.42 When is 52 weeks not equal to a year? Refer to the previous exercise.
