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 7.6 minutes and a standard deviation of 2.3 minutes. For a randomly received emergency call, find the following probabilities. (For each answer, enter a number. Round your answers to four decimal places.)
(a) the response time is between 3 and 9 minutes
(b) the response time is less than 3 minutes
(c) the response time is more than 9 minutes
use technology to construct the confidence intervals for the population variance ?2 and the population standard
What parametric test could be used to test for the effect of linoleic acid on SBP? Perform the test in Problem 1, and report a p-value. What nonparametric test could be used to test for the effect of linoleic acid on SBP?

For the uniform distribution over the interval -3 to 2, determine (a) P(X ≤ 1), (b) P(X 0), (d) P(-1.2 ≤ X ≤ 1), (e) P(X = 1).
At the .05 significance level, is there a difference in the mean number of calls per day between the two employees?
For a hypothesis test about a population proportion or mean, if the level of significance is less than the p-value, the null hypothesis is rejected.
A university found that 20% of its students withdraw without completing the introductory statistics course. Assume that 20 students registered for the course.
In this problem, we develop a weak law of large numbers for a correlated sequence X1, X2,... of identical random variables. In particular, each Xi has expected value E[Xi] = µ, and the random sequence has covariance function
For machine gun ammunition to be acceptable, the US Army requires that 96 percent of rounds fired hit a specified target. The test is to fire a 50 round burst at the target and observe whether this condition is met.
Determine the z value used to build a 90% confidence interval estimate of the population proportion. Give the positive value answer exactly as found from tables (three decimal places).
