Transcribed Image Text: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 n, = 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 n, = 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.

males aged 60-65 initially suffering from high blood pressure.
