Diane Bruns is the mayor of a large city. Lately, she has become concerned about the possibility that large numbers of people who are drawing unemployment checks are secretly employed. Her assistants estimate that 40 percent of unemployment beneficiaries fall into this category, but Ms. Bruns is not convinced. She asks one of her aides to conduct a quiet investigation of 10 randomly selected unemployment beneficiaries. If the mayor’s assistants are correct, what is the probability that one or three of the investigated individuals have jobs?

According to the Chronicles of Contrived Statistics (March, 2016), the probability that Elon Musk will offer you a free trip into space in the next month is 26%. The probability that scientists from Area 51 will start selling pet aliens next month is 31%. Finally, the probability that either Elon Musk will offer you a free trip to space or that scientists will begin sales of pet aliens next month is 11%. What is the probability that both Elon Musk will offer you a free trip into space and scientists from Area 51 will start selling pet aliens in the next month? Answer in decimal form. Round to two decimal places as needed. Your Answer:
It is known that the use of banned drugs can contribute to mental illness. The minister of health wants to put a cost to this disaster and request that you take a study. In Barbados 40% of mentally ill blame their illness on drugs. Without previous knowledge in Jamaica we assume that this is the same proportion here. You selected a random sample of 12Bellevue patients to review. What is the probability that 6 patients used the drugs that caused their illness.

In an article that appears on a website,† Carlton Gunn, a public defender in Seattle, Washington, wrote about how he uses statistics in his work as an attorney. He states the following. I personally have used statistics in trying to challenge the reliability of drug testing results. Suppose the chance of a mistake in the taking and processing of a urine sample for a drug test is just 1 in 100. And your client has a "dirty" (i.e., positive) test result. Only a 1 in 100 chance that it could be wrong? Not necessarily. If the vast majority of all tests given—say 99 in 100—are truly clean, then you get one false dirty and one true dirty in every 100 tests, so that half of the dirty tests are false. Define the following events as given below. TD = event that the test result is dirty TC = event that the test result is clean D = event that the person tested is actually dirty C = event that the person tested is actually clean (a) Using the information in the quote, compute the following…

We believe that 95% of the population of all Elementary Statistics students consider Statistics an exciting subject. Suppose we randomly and independently selected 20 students from the population. If the true percentage is really 95% find the probability of observing 19 or more of the students who consider statistics to be an exciting subject in our sample of 20.
A recent study has shown that approximately 31.6% of Canadians are considered 'supertasters,' or people who experience the sense of taste with greater intensity than average. Consider a sample of 23 Canadians, each of whom are asked to indicate if they are a supertaster or not. Please use this information to answer the following questions.a. Suppose you know that at least 7 of the Canadians sampled are supertasters. What is the probability that exactly 15 of the Canadians sampled are supertasters?Answer:______________Round to at least FOUR digits after the decimal if necessary. b. What is the probability that the 10th Canadian sampled is the sixth person to indicate that they are a supertaster?Answer:______________Do NOT round your answer; give all the decimals.
What are the reasoning or arguments surrounding the below statement: "Statistical research shows that the probability of a person who takes one alcoholic drink are at a greater risk of getting into a car accident than someone who recently smoked marijuana
Determining the prevalence of illicit substances in society can be very difficult. Simply looking at police records doesn’t give the whole picture, and any surveys designed to determine usage are subject to all sorts of biases. In particular, if responding “yes” to a particular question carries with it a stigma or implication of guilt, then many respondents will lie. To alleviate this issue, we can use a survey design that is based on conditional probability. Suppose we want to estimate the proportion of the Helena population who have used marijuana within the last month. We select 4744 participants and ask them each to first privately draw a card from a standard 52-card deck.* If they get a “club” they are asked to respond truthfully to the question “Have you used marijuana within the last month?”* If they get any other suit they are asked to respond to the question “Does your phone number end in an odd digit?” The study is blinded in the sense that the researcher doesn’t know which…
A radio talk show asks listeners to call in and say whom they are going to vote for in the next presidential election. Of the 587 callers, 71% say they favor one of the candidates, while 29% favor the other. Does this convince you that the first candidate is likely to win the election? Why or why not? What is statistical issue is involved here?
Consider records of a company’s account balances. Twenty percent contain errors. Of those balance in errors, 80% are regarded as unusual values based on historical figures. Of all the account balances, 25% were unusual values. If the figure for a particular balance appears unusual on this basis, what is the probability that it is in error?
