*AARP reported that the average senior citizens living at high altitudes claim their systolic blood pressure is lower than the average of 160. To test this claim,
16 senior citizens living at high altitudes were selected at random and their blood pressures checked. Their mean systolic pressure was 151, the standard
deviation for the sample was 12. Do senior citizens living at high altitudes have significantly lower systolic blood pressure? Use the 0.05 level of significance.
