Exercise 4

a) Using the “Exercise_4.sav” data file, select the appropriate statistical technique to test the hypothesis that there is no difference in systolic blood pressure due to an intervention of diet and aerobic exercise training lasting 6, 12 and 24 weeks.  Group 1 performs the intervention for 6 weeks, group 2 for 12 weeks and group 3 for 24 weeks.  Report and interpret your findings and consider the use of post hoc tests to provide additional information.
