Question
Paired T for before-after N Mean St.Dev. SE Mean Before 3 150.0 15 8.660 After 3 130.0 10 5.774 diffrence 3 20.0 5 2.887 T-test of mean diffrence= 0(vs not= 0): T-value = 6.93 P-value = 0.020 b) Explain how to interpret the P-value. A. H0 : m1 = m2HA : m1 = m2 B. The p-value is less than the significance level(assumed to be 95%) and therefore we can reject H0 and say the exerciseprogram does seem beneficial to lowering bloodpressure. C. The samples are independent. D. The samples are dependent. Paired T for before-after N Mean St.Dev.
