- When playing the game clash of clans, red army six has earned three stars during 47 of her last 63 war attacks what is the empirical probability she will earn three starsWhat are the chances that a person who is murdered actually knew the murdered? The answer to this question explains why a lot of police detective work begins with relatives and friends of the victim. About 64% of people who are murdered actually knew the person who committed the murder. Suppose that a detective has 63 current unsolved murders. Explain why this is a binomial experiment.Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression. What is the probability of a person developing dementia? If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?
- Based on historical data, your manager believes that 26% of the company's orders come from first-time customers. A random sample of 146 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.28 and 0.46?Based on historical data, your manager believes that 34% of the company's orders come from first-time customers. A random sample of 175 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is less than 0.33?A binomial experiment consists of 19 trials. The probability of success on trial 12 is 0.45. What is the probability of success on trial 16?
- Based on historical data, your manager believes that 25% of the company's orders come from first-time customers. A random sample of 79 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is less than 0.31?In a recent year, the Better Business Bureau settled 75% of complaints they received. You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Suppose your sample size is 299. What is the probability that the sample proportion will be at least 5 percent more than the population proportion?A drug manufacturer claims that their drug cures a certain blood disease 78% of the time. To check the claim, BFAD used the drug in a clinical trial of 100 individuals inflicted with the disease and decided to accept the claim if 70 or more are cured. What is the probability that the claim will be accepted when the cure probability is as low as 0.6?
