Q9 We want to test whether the response time for the police during an emergency in Australia meetsthe target of 12 minutes. To test this hypothesis, we take a sample of the response times for police inall 141 counties of NSW.The mean of the sample times was found to be = 11.7 minutes and the standard deviation wasminutes.2.5What is the p-value?

We want to test whether the response time for the police during an emergency in Australia meets the target of 12 minutes. To test this hypothesis, we take a sample of the response times for police in all 141 counties of NSW. The mean of the sample times was found to be = 11.7 minutes and the standard deviation was o = 2.5 minutes. What is the p-value? What can you conclude from this p-value? The following information might be useful: P(Z > 0.12) = 0.4522 P(Z > 0.39) 0.3483 P(Z > 1.17) = 0.1210 P(Z > 1.42) = 0.0778 p-value = P(Z > 0.12) = 0.45. We conclude that the population mean response time is less than 12 minutes. p-value = P(Z > 0.39) = 0.35. We conclude that the population mean response time is less than 12 minutes. p-value = minutes. - P(Z < -1.17) = 0.12. p-value = minutes. *P(Z < -1.42) = 0.08. None of the above We conclude that the population mean response time is not less than 12 We conclude that the population mean response time is not less than 12
