Independent random samples are selected from two populations

Independent random samples are selected from two populations and are used to test the hypothesis Ho: (u1-H2-0 against the alternative H (u1-H2 0. An analysis of 234 observations from population 1 and 313 from population 2 yielded a of 0.113. Complete parts a below. a. Interpret the results of the computer analysis. Useas0.10. A. Since the given a value exceeds this p-value, here is insufficient evidence to indicate that the population means are different. OB. this p-value exceeds the given value of o, there is suficient evidence to indicat that the population means are different. Oc this p value exceeds the given value of o, there is insufficient evidence to indicate that the population means are different. D. Since the given a value exceeds this p-value, there is sufficient evidence to indicate that the population means are different. b. If the alternative hypothesis had been H u2)

Solution

(a) C

(b) The p-value= 0.113/2 = 0.1
