Police response time to an emergency call is the difference between the time the call is first received by the dispatcher and the time a patrol car radios that it has arrived at the scene. Over a long period of time, it has been determined that the police response time has a normal distribution with a mean of 8.6 minutes and a standard deviation of 1.5 minutes. For a randomly received emergency call, find the following probabilities. A) the response time is between 2.75 and 4.05 minutes. Keep your answer in 4 decimal places. B) the response time is 7.25 to 11.65 minutes. Keep your answer in 4 decimal places. C) the response time is anywhere from 7.85 to less than 15.35 minutes. Keep your answer in 4 decimal places. D) the response time is anywhere greater than 9.25 to 11.65 minutes. Keep your answer in 4 decimal places. **Notes: DO NOT round any z-score.
