88, 76, 69, 78, 74, 85, 79, 78, 80, 81

Does the new birth control pill affect blood pressure (m = 75)? the new birth control pill affect blood pressure (m = 75)? Complete a 6-step hypothesis test with alpha = .05.

3. Critical value: 2.262
4. Statistic: t = 2.246
5. Decision: Fail to reject the null hypothesis.
