Suppose that a group of illegal counterfeiters print 1,000 copies of fake $20 bills and introduces them into theeconomy. Suppose that each bill is used once per week (starting in week 1), and that each time a bill is used, ithas a 1 in 5 chance of being detected as fake. If it is detected, it is removed. If not, it is used again.kn-1(a)What does the expression E 1000 (" ) represent? Explain.n=1Suggestion: If you are unsure, try writing out the expression for n = 1,2, 3 and consider what these mightrepresent.

Answered: Suppose that a group of illegal…

Suppose that Fred, a United States politician from a large western state, wants to create a new law that would require children under the age of 16 to be accompanied by an adult at all times in public places. Based on previous voting records, Fred believes that he could gain the support of 2525% of likely voters. To test his hypothesis, Fred conducts a random survey of 12001200 likely voters and asks if they would support his proposition. Let ?X denote the number of likely voters in Fred's sample that pledge their support, assuming that Fred's belief that 25%25% of likely voters would support his proposal. Which of the following statements are true about the sampling distribution of ?X? -The sampling distribution of ?X is approximately binomial with ?=1200n=1200 and ?=0.25p=0.25. -The sampling distribution of ?X is exactly normal with ?=0.5μ=0.5 and ?=0.0125σ=0.0125. -The sampling distribution of ?X is exactly binomial with ?=1200n=1200 and ?=0.25p=0.25. -The sampling…
8* A medical researcher estimates that 2% of a population is infected with a rare disease which for this problem we will assume is accurate. The procedure used for testing for this disease is 90% accurate. So, if one has the disease, the test will indicate that 90% of the time, and if the person doesn't have the disease, the test will indicate that 90% of the time. Of course, what this means is that the test will give a false positive result 10% of the time. If a person is picked at random and tested: (a) What is the probability that the person tests positive? (b) What is the probability that if a person tested positive for the disease he or she actually had the disease?

In a recent study, 50 males used a new weight-loss supplement, and 37 of them experienced weight loss after two weeks. In the same study, 25 females used the same supplement, and 16 of them experienced weight loss after two weeks. Fill in the blanks below to make the most reasonable statement possible The new weight-loss supplement was more effective on males or females in the study. That is because _______% only failed to lose weight after two weeks, whereas, _______ % of males or females failed to lose weight after two weeks
Rework problem 29 from section 4.1 of your text about the professor who sometimes forgets to bring her briefcase to the office, but assume that, each day, the probability that she forgets the briefcase is 1/8. Assume that her forgetting is a Bernoulli process. (1) What is the probability that she remembers to bring her briefcase every day in one week (5 days)? (2) What is the probability that she forgets to bring her briefcase every day in one week (5 days)? (3) What is the probability that she forgets to bring her briefcase at least one day in one week (5 days)?
