A statistical program is recommended. Jensen Tire & Auto is in the process of deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine. Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars). Weekly Usage(hours) AnnualMaintenanceExpense 13 17.0 10 22.0 20 30.0 28 37.0 32 47.0 17 30.5 24 32.5 31 39.0 40 51.5 38 40.0 #1) Develop the estimated regression equation that could be used to predict the annual maintenance expense (in hundreds of dollars) given the weekly usage (in hours). (Round your numerical values to two decimal places.) #2) The expected expense of a machine being used 34 hours per week is $ hundred.
A mutual fund is a professionally managed investmentscheme that pools money from many investorsand invests in a variety of securities.

Q1: Adolescent obesity is a serious health risk affecting more than 5 million young people in the United States alone. Laparoscopic adjustable gastric banding has the potential to provide a safe and effective treatment. Fifty adolescents between 14 and 18 years old with a body mass index higher than 35 were recruited from the Melbourne, Australia, community for the study. Twenty-five were randomly selected to undergo gastric banding, and the remaining 25 were assigned to a supervised lifestyle intervention program involving diet, exercise, and behavior modification. All subjects were followed for two years. b. Without assuming the two groups having equal variances, give a 95% confidence interval for the mean weight loss difference between the gastric banding and intervention group. c. Test if gastric banding leads to greater weight loss than the lifestyle intervention program, give H0, Ha, test statistic, p-value, conclusion and 95% CI for the mean weight loss difference. d. Now…

A hospital conducted a study of the waiting time in its -emergency room. The hospital has a main campus and three -satellite locations. Management had a business objective of reducing waiting time for emergency room cases that did not require immediate attention. To study this, a random sample of 15 emergency room cases that did not require immediate attention at each location were selected on a particular day, and the waiting times (measured from check- in to when the patient was called into the clinic area) were collected and stored in the table. a) At the 0.05 level of significance, is there evidence of a difference in the mean waiting times in the four locations?

A development corporation purchased land that will be the site of a new luxury condominium complex. Management is considering a six month market research study designed to learn more about potential market acceptance of the condominium project. Management anticipates that, if conducted, the market research study will provide one of the following two results. 1. Favorable report (F): A significant number of the individuals contacted express interest in purchasing a condominium. 2. Unfavorable report (U): Very few of the individuals contacted express interest in purchasing a condo- minium. After deciding whether to conduct the market research study, they have the following two decision alternatives. d1 = a small complex with 30 condominiumsd2 = a medium complex with 60 condominiumsFollowing this, a chance event concerning the demand for the condominiums has two states of nature. s1 = strong demand for the condominiumss2 = weak demand for the condominiumsThe payoffs, probabilities, and…
