A study aims to determine the relationship of salt intake to the blood pressure of persons aged 15 years and over. The mean systolic blood pressure (SBP) of 20 subjects with a low salt diet was compared to that of an equal number of subjects with a high salt diet. With the given data, test the hypothesis that the mean SBP of subjects with high salt diets is significantly higher than those with low salt diets. High Salt Diet 140 mmHg 9.6 mmHg Low Salt Diet 135 mmHg 14.4 mmHg Mean SBP Std. dev. of SBP
