Three television pilots for potential situation-comedy series were shown to audiences in four regions of the country—the East, the South, the Midwest, and the West Coast. Based on audience reactions, a score (on a scale from 0 to 100) was obtained for each show. The sums of squares between groups

(shows) and between blocks (regions) were found to be SSG = 95.2 and SSB = 69.5 and the error sum of squares was as follows:

SSE = 79.3 Prepare the analysis of variance table, and test the null hypothesis that the population mean scores for audience reactions are the same for all three shows.
