True average lumen outputs

Reference no: EM1394325

The lumen output was determined for each of c = 3 different brands of 60-Watt soft-white light bulbs, with 8 bulbs of each brand tested. The sums of squares were computed as SSW = 4773.3 and SSA = 591.2. Use the F test of ANOVA (assume α = 0.05) to decide whether or not there are any differences in true average lumen outputs between the three brands for this type of light bulb.
