A research group wishes to conduct a randomized trial to compare a new medication to a medication they consider standard care. One hundred patients with hypertension are enrolled and randomized to one of the two comparison treatments. After taking the assigned medication for 6 weeks, their systolic blood pressure (SBP) is measured. Summary statistics are given here. Use the data to test if there is a significant difference in systolic blood pressures between medication groups assuming equality of the variances. Run the appropriate test at a 5% level of significance. Treatment Number of Patients Mean SBP Standard Deviation New 50 130 12 Standard 50 135 10
