Probability= DII In the game of blackjack as played in casinos in Las Vegas, Atlantic City, Niagara Falls, as well as many other cities, the dealer has the advantage.

Swimsuits A swimsuit manufacturer wants to test thespeed of its newly designed suit. The company designs an experiment by having 6 randomly selected Olympic swim-mers swim as fast as they can with their old swimsuit first and then swim the same event again with the new, expen-sive swimsuit. The company will use the difference in times as the response variable. Criticize the experiment and pointout some of the problems with generalizing the results.
show all solution It is useful for Fire Departments to have a model for X=number of direct injuries occurring in a fire incident. They can use this to determine the level of medical services to make available each time. Suppose the pmf of X is as follows: x 0 1 2 3 4 5 6 7 8 9 f(x) .08 .09 .09 .14 .18 .16 .09 .06 .06 .05 Use this pmf to determine the probabilities of the following events: event that there will be at least 1 direct injury event that there will less than 3 direct injuries event that there will be more than 2 but less than 8 direct injuries

TRY IT 4.1 A hospital researcher is interested in the number of times the average post-op patient will ring the nurse during a 12- hour shift. For a random sample of 50 patients, the following information was obtained. Let X = the number of times a patient rings the nurse during a 12-hour shift. For this exercise, x = 0, 1, 2, 3, 4, 5. P(x) = the probability that X takes on value x. Why is this a discrete probability distribution function (two reasons)? P(x) 4 P(x = 0) = 50 8 1 P(x = 1) = 50 16 2 P(x = 2) = 50 14 P(x = 3) = 50 6 4 P(x = 4) = 50 5 P(x = 5) = 50 Table 4.3 3. LO
