The lumen output was determined for each of I 5 3 differentbrands of lightbulbs having the same wattage, withJ 5 8 bulbs of each brand tested. The sums of squareswere computed as SSE 5 4773.3 and SSTr 5 591.2.State the hypotheses of interest (including word definitionsof parameters), and use the F test of ANOVA(a 5 .05) to decide whether there are any differences intrue average lumen outputs among the three brands forthis type of bulb by obtaining as much information aspossible about the P-value
