Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 40 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, what is the estimate of the P-value of the test? 0.060.080.140.28 60% 62% 64% 66% 68% 70% 72% 74% 76% 78% 80% 82% 84% 86% 88%Simulated sample proportion of good servesO 0.060.08D 0.14O 0.28000000000000000000000000000000000000000-+00000000000000000000+0000000+

Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 40 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H₀: p = 72% and H_a: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, what is the estimate of the P-value of the test?
