Question
The lumen output was determined for each of J = 3 different brands of 60-watt soft-white lightbulbs, with J = 9 bulbs of each brand tested. The sums of squares were computed as SSE = 47/2.8 and SSTr = 594.8. State the hypotheses of interest (including word definitions of parameters). Use the F test of ANOVA (a = 0.05) to decide whether there are any differences in true average lumen outputs among the three brands for this type of bulb by obtaining as much information as possible about the P-value. (Round your answer to two decimal places.)Explanation / Answer
