Hello I am having trouble with questions 6-9. If you could help that would be great!

1. In a study to investigate the effect of regular physical exercise on the reduction of high blood pressure in males aged 60-65, the researchers selected at random a sample of #, = 12 males suffering from high blood pressure in the given age group and for a two-year period placed the subjects on a daily physical exercise program. A second sample of a, = 12 males suffering from high blood pressure in the given age group was selected and again for the two-year period this group of subjects were placed on a physical exercise program for which they were required to perform only once a week. Finally a third sample of n, -12 males suffering from high blood pressure in the given age group was selected. No exercise program was required for individuals in sample three. At the end of the two-year period the reduction in blood pressure was measured for each of the subjects in the study and is presented in the table on the next page. Table V.1: Reduction in Blood pressure for three groups of males aged 60-65 initially suffering from high blood pressure.
