A emergency center ensures that the average response time for the calls received is less than 75 seconds. To
corroborate this statement, an external agency collects a sample of 90 calls. For this sample, the average
response time was 70 seconds with a standard deviation of 15 seconds. Does the collected information match the claim of the center? Show your work. If needed use a level of significance = 0:05

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 8.8 minutes and a standard deviation of 1.9 minutes. For a randomly received emergency call, find the following probabilities. (Round your answers...
