Describe Hypothesis testing with one way ANOVA.
29 arbitrarily selected subjects were exposed to commercials shown in more involving programs. (2) 29 arbitrarily selected subjects were exposed to commercials shown in less involving programs and (3) 29 arbitrarily selected subjects watched commercials only (note: this is called the control group). The mean brand remembrance scores for these three groups were respectively X1-bar = 1.21, X2-bar= 2.24, and X3-bar = 2.28. Also a one-way ANOVA of the data shows that SST = 21.40 and SSE = 85.56.
Describe appropriate treatment means μ1, μ2 and μ3. Then Test for statistically important differences between these treatment means. Set α = 0.05
