A researcher conducts an independent-measures study. One sample of individuals serves as a control group and another sample serves as a treatment group. The researcher hypothesizes that the two samples will be different on the dependent variable. The data are as follows: Control Treatment n = 6 n = 9 M = 56 M = 62 SS = 470 SS = 700 α = .05, two-tailed a.) Following the steps of a hypothesis test, first determine whether the two groups...
