1. A researcher is interested in testing two different dosagesof a new sleeping medication in a phase II clinical trial against acontrol group receiving a placebo. Suppose the following tableobserves the hours of sleep reported the preceding evening forsubjects randomly assigned to each of the three groups. α = .05Dosage One 8.5, 7.9, 8.6, 8.4, 7.6, 9.1.Dosage Two- 8.1, 7.9 , 7.9, 7.6, 7.4.Control Group- 5.2, 5.6, 5.7, 5.9, 6.2, 6.4,6.1.
A) Calculate the MSB and MSW for a one-way analysisof variance procedure. B) Using the information above, calculate anF statistic, and provide an interpretation of yourp-value. (Continue as though all assumptions forANOVA are met). How would you solve this without usingexcel?
