Pest Control In an experiment to test the effectiveness of the latest roach trap, the "Roach Resort," 500 roaches were placed in the vicinity of the trap and left there for an hour. At the end of the hour, it was observed that 20 of them had "checked in," while the rest were still scurrying around. (Remember that "once a roach checks in, it never checks out." Let 1 not checked in, and 2 = checked in.) (a) Set up the transition matrix P for the system with decimal entries. 0.96 0 Calculate p² 0.9216 0 0.04 1 0.0784 1 Calculate p3 0.884736 0 0.1168 x 1 (b) If a roach begins outside the "Resort," what is the probability of it "checking in" by the end of 1 hour? 2 hours? 3 hours? 1 hour 0.04 2 hours 0.0784 3 hours 0.1168 (c) What do you expect to be the long-term impact on the number of roaches? Eventually, all the roaches will have checked in. Eventually, all the roaches will not have checked in. There is not enough information.

Jerry is considering opening a new ice cream store at a certain location on State Street in Madison. Jerry conducts some analysis and determines that a given location is acceptable only if the number of pedestrians passing the potential location averages more than 100 per hour. To check if this location is acceptable, Jerry records the number of pedestrians observed for each of 40 hours. Jerry finds that the average number of pedestrians that pass the potential location during each of the 40 hours he was observing, is 105.7 per hour. Jerry assumes that he knows the population standard deviation to be 16. Can Jerry conclude at the 1% significance level that the potential location for the ice cream store is acceptable? a. What is the correct set of hypotheses? Answer: Ho: u = 100 and H1: u> 100 v b. Determine the p-value Answer: 0.0122 c. Interpret the results Answer: There is not enough evidence d.

The manager of a local record store is interested in the effectiveness of an advertisingcampaign on sales. They randomly select 10 popular CDs (all in the Billboard top 100),and place an ad in the local school newspaper saying that the store has these (and more)in stock. They measure the sales of these 10 CDs for 1 week prior to the ad, and then for1 week after the ad. The number of CDs sold each week is presented below. Was there anincrease in the number of CDs sold after the ad?

A certain affects virus 0.8% of the population. A test used to detect the virus in a person is positive 88% of the time if the person has the virus (true positive) and 13% of the time if the person does not have the virus (false postive). Fill out the remainder of the following table and use it to answer the two questions below. (enter answer with no commas, i.e. as 1000 not 1,000.)
