Famous psychic, television personality Sylvia Browne is invited to Oprah Winfrey
show to demonstrate her gift in a live TV broadcast. The process entails asking Sylvia
a series of 20 independent questions with yes/no answers. The questions would be
of the nature that she could not have any way of knowing the answer from prior
knowledge. Suppose that Sylvia correctly answered 15 of the 20 questions, which of
the following would be a viable conclusion to reach?
If she were guessing, 15 is within one standard deviation of the mean and
therefore she must not have any special psychic abilities.
Because the probability of getting 15 or more correct is 0.0207, it is likely that
she is just guessing at the questions.
Because the probability of guessing exactly 15 correct is 0.0148, she must just
be guessing.
Because the probability of guessing 15 or more correctly is 0.0207, it is unlikely
that she is guessing at the questions and may, in fact, have some special ability.

Some citizens complained to city council members that there should be equal protection under the law against the occurrence of crimes. The citizens argued that this equal protection should be interpreted as indicating that high-crime areas should have more police protection than low-crime areas. Therefore, police patrols and other methods for preventing crime (such as street lighting or cleaning up abandoned areas and buildings) should be used proportionately to crime occurrence.
The city has been broken down into 20 geographic areas, each containing 5,000 residences. The police recognize that not all crimes and offenses are reported: people do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone a random sample of 1,000 of the 5,000 residences for data on crime. (Respondents are guaranteed anonymity.) The 1,000…

- It costs a pharmaceutical company 75,000 to produce a 1000-pound batch of a drug. The average yield from a batch is unknown but the best case is 90% yield (that is, 900 pounds of good drug will be produced), the most likely case is 85% yield, and the worst case is 70% yield. The annual demand for the drug is unknown, with the best case being 20,000 pounds, the most likely case 17,500 pounds, and the worst case 10,000 pounds. The drug sells for 125 per pound and leftover amounts of the drug can be sold for 30 per pound. To maximize annual expected profit, how many batches of the drug should the company produce? You can assume that it will produce the batches only once, before demand for the drug is known.arrow_forwardSuppose that a regional express delivery service company wants to estimate the cost of shipping a package (Y) as a function of cargo type, where cargo type includes the following possibilities: fragile, semifragile, and durable. Costs for 15 randomly chosen packages of approximately the same weight and same distance shipped, but of different cargo types, are provided in the file P13_16.xlsx. a. Estimate a regression equation using the given sample data, and interpret the estimated regression coefficients. b. According to the estimated regression equation, which cargo type is the most costly to ship? Which cargo type is the least costly to ship? c. How well does the estimated equation fit the given sample data? How might the fit be improved? d. Given the estimated regression equation, predict the cost of shipping a package with semifragile cargo.arrow_forwardSome citizens complained to city council members that there should be equal protection under the law against the occurrence of crimes.

Mike earns a bonus each year based on revenue generated by the number of vehicles sold in the year less related warranty expenses. The quality of automobiles sold each year seems to vary since the warranty experience related to vehicles sold is highly variable. The actual warranty expenses have varied over the past 10 years from a low of 3% of an automobile’s selling price to a high of 10%. In the past, Mike has tended toward estimating warranty expenses on the high end just to be prudent. It is the end of the year and once again he must work with the dealership’s accountant in arriving at the warranty expense accrual for the cars sold this year. Required 1. Does the warranty accrual decision present any kind of ethical dilemma for Mike Thatcher? 2. Since the warranty experience is not constant, what percent do you think Mike should choose for this year?
