Question:
A health care professional wants to determine whether individuals with hypertension who take Atenololhave significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 163 (= 163) with a standard deviation of 13. The 30 individuals who take Atenololhave an average (mean) systolic blood pressure of 146.On the basis of these data, can the researcher conclude that the Atenololsignificantly lowers systolic blood pressure? (Use these numbers only for this question!)
