Transcribed Image Text: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. (Use i = 1, 2, 3, and 4 for A, B, C, and D respectively.) A: 11 5 12 14 9 B: 15 11 16 10 C: 13 19 10 16 19 D: 16 15 11 22 14 n USE SALT It is believed that the number of flaws has approximately a Poisson distribution for each brand. Analyze the data at level 0.01 to see whether the expected number of flaws per reel is the same for each brand. State the appropriate hypotheses. O Ho: H1 + H2 # Hz # H4 H: at least two u's are equal O Ho: H1 = H2 = H3 = H4 H: all four u's are unequal O Ho: H1 # Hq # Hz# H4 H: all four u,'s are equal O Ho: H1 = H2 = "3 = H4 H: at least two u's are unequal Calculate the test statistic. (Round your answer to two decimal places.) f = What can be said about the P-value for the test? O P-value > 0.100 O 0.050 < P-value < 0.100 O 0.010 < p-value < 0.050 O 0.001 < P-value < 0.010 O P-value < 0.001
