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 8.4 minutes and a standard deviation of 1.7 minutes.

1.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 8.4 minutes and a standard deviation of 1.7 minutes.For a randomly received emergency call, what is the probability that the response time will be less than 5 minutes?

Select one or more:

a.-2.00

b.0.02275

c.0.0455

d.-0.2275

2.For a randomly received emergency call, what is the probability that the response time will be between 5 and 10 minutes?

Select one or more:

a.0.0228

b.0.8039

c.0.1733

d.0.8267

3.To review their effectiveness, the police chief periodically takes a simple random sample of 25 calls and computes the sample mean.What is the probability that the mean response time will be between 5 and 10 minutes?

Select one or more:

a.0.1792

b.0.9999

c.0.8039

d.0.0001

4.Why did the probability increase from number 2 to number 3?Explain well, referencing the Central Limit Theorem.
