A reseаrcher clаims thаt the mean systоlic blооd pressure for women is lower than the mean systolic blood pressure for men. He selects random samples of 500 women and 500 men. For the sample of women, the mean is 121 mm Hg with a standard deviation of 32 mm Hg, and for the sample of men, the mean is 124 mm Hg with a standard deviation of 30 mm Hg. What is the approximate p-value for the appropriate test of the researcher’s claim?
