Laura Naples, manager of Heritage Inn, periodically collects and tabulates information about a sample of the hotel’s overnight guests. This information aids her in pricing and scheduling decisions she must make. The table below lists data on 10 randomly selected hotel registrants, collected as the registrants checked out. The data listed are: Number of people in the group Hotel’s shuttle service used: yes or no Total telephone charges incurred Reason for stay: business or personal *Insert hw.png 1. Before cell telephones became so common, the average telephone charge per registered group was at least $5.00. Laura suspects that the average has dropped. Test H0: m > 5 and Ha: m < 5 using a .05 level of significance. Use both the critical value and p-value approaches to hypothesis testing. 2. In the past, Laura has made some important managerial decisions based on the assumption that the average number of people in a registered group is 2.5. Now she wonders if the assumption is…
It is a common belief that SUVs are safer than cars. In a collision, does an SUV sustain less damage (cost of repair) than a car?

A transportation engineer at OSU conducts a study on bus ridership to the 14th and Monroe bus stop near campus. They collect data from riders by surveying every 10th person who arrives at the bus stop, and end up with a sample of 138 people. For each person surveyed, they collect the following information: OSU student (yes/no) Distance traveled to get to campus (miles) Number of bus rides per week Satisfaction with bus service (very unsatisfied, unsatisfied, neutral, satisfied, very satisfied) What sampling scheme is the engineer using to collect data? Simple random sampling Stratified sampling Systematic sampling Convenience sampling
According to the American Management Association, most U.S. companies now test at least some employees and job applicants for drug use. The U.S. National Institute on Drug Abuse claims that about 15% of people in the 18-25 age bracket use illegal drugs. Allyn Clark, a 21 year-old college graduate, applied for a job at the Acton Paper Company, took a drug test, and was not offered a job. He suspected that he might have failed the drug test, even though he does not use drugs. In checking with the company's personnel department, he found that the drug test has 99% sensitivity, which means that only 1% of drug users incorrectly test negative. Also, the test has 98% specificity, meaning that only 2% of nonusers are incorrectly identified as drug users. Allyn felt relieved by these figures because he believed that they reflected a very reliable test that usually provides good results. But is this really true? The accompanying table shows data for Allyn and 1,499 other job applicants. Based…
A nonprofit organization conducted a survey of 2040 metropolitan-area teachers regarding their beliefs about problems that hamper students' schooling. The following data were obtained. 850 said that lack of parental support is a problem. 850 said that abused or neglected children are problems. 660 said that malnutrition or students in poor health is a problem. 110 said that lack of parental support and abused or neglected children are problems. 100 said that lack of parental support and malnutrition or poor health are problems. 130 said that abused or neglected children and malnutrition or poor health are problems. 20 said that lack of parental support, abuse or neglect, and malnutrition or poor health are problems. What is the probability that a teacher selected at random from this group said that lack of parental support is the only problem hampering students' schooling? Hint: Draw a Venn diagram. (Round your answer to three decimal places.)
