Question

An analysis of variance is used to evaluate the mean differences for a research study comparing four treatments with a separate sample of n = 8 in each treatment. If the data produce an F-ratio of F 4.60, which of the following is the correct statistical decision? a. Reject the null hypothesis with a = .05 but not with a = .01 b. Reject the null hypothesis with cither a = .05 or a = .01 c. Fail to reject the null hypothesis with either a = .05 or a = .01 d. There is not enough information to make a statistical decision

Explanation / Answer

here p value with 3 and 28 degree of freedom and above F value =0.0097

as p value is less then both 0.05 and 0.01

hence option b is correct
