Question

The lumen output was determined for each of 1 3 different brands of lightbulbs having the same wattage, with J- 10 bulbs of each brand tested. The sums of squares were computed as SSE 4772.6 and SSTr 593.5. State the hypotheses of interest (including word definitions of parameters) -sample average lumen output for brand i bulbs Hai all three 's are unequal ' = true average lumen output for brand i bulbs Hai at least two 's are unequal 0 ' = sample average lumen output for brandi bulbs Hai all three 's are equal 0 ' = true average lumen output for brand i bulbs Ha: at least two 's are equal Use the F test of ANOVA ( = 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

here test statistic F=MStr/MSE =(593.5/2)/(4772.6/27) =1.68

for 0.05 level and (2,27) degree of freedom crtiical F for rejection region =3.35
