The previous average response time for emergency vehicles was 5 minutes. A recent sample found the following response times (minutes):

4.23   5.14   4.85   3.25   1.56   6.22   5.05   4.23   3.89   3.33   2.85   5.56   2.50

A. What is the average response time for the sample?

B. What is the standard deviation for all samples of response times of this sample size?

C. Assuming α = 2.5%, what is the value of the test statistic for this hypothesis test?

D. What is the p-value for this left tailed hypothesis test?

E. Assuming α = 2.5%, what is the conclusion for this hypothesis test?

F. Assuming α = 1%, what is the conclusion to this hypothesis test?

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...
