In an experiment to compare the quality of four different brands of magnetic recording tape, five 2400-ft reels of each brand (A-D) were selected and the number of flaws in each reel was determined.

It is believed that the number of flaws has approximately a Poisson distribution for each brand. Analyze the data at level .01 to see whether the expected number of flaws per reel is the same for each brand?
