The owner of a restaurant in Bloomington, Indiana, has recorded sales data for the past 19 years. He has also recorded data on potentially relevant variables. The data are listed in the file P13_17.xlsx. a. Estimate a simple regression equation involving annual sales (the dependent variable) and the size of the population residing within 10 miles of the restaurant (the explanatory variable). Interpret R-square for this regression. b. Add another explanatory variableannual advertising expendituresto the regression equation in part a. Estimate and interpret this expanded equation. How does the R-square value for this multiple regression equation compare to that of the simple regression equation estimated in part a? Explain any difference between the two R-square values. How can you use the adjusted R-squares for a comparison of the two equations? c. Add one more explanatory variable to the multiple regression equation estimated in part b. In particular, estimate and interpret the coefficients of a multiple regression equation that includes the previous years advertising expenditure. How does the inclusion of this third explanatory variable affect the R-square, compared to the corresponding values for the equation of part b? Explain any changes in this value. What does the adjusted R-square for the new equation tell you?

You are welcome to use a spreadsheet). b) Does the correlation imply that the miracle shakes cause weight loss? Identify any possible outliers.

There is only one payroll training tax in North America. The Quebec government program that forces employers to spend 1 percent of payroll on training may not have the intended consequences of increasing training investments in employees. Using data from a Statistics Canada survey, Alan Saks of the University of Toronto and Robert Haccoun of the Université de Montréal matched Quebec employers with Ontario employers and found that there were no differences in amounts spent on training. The paperwork is so cumbersome that many employers prefer to pay the 1 percent tax rather than go through the thick guidebooks necessary to report the training. There are many other mandatory training programs across Canada. In addition to legal requirements in posting information on employment standards, occupational health and safety, accessibility, pay equity plans, workplace violence policies, among others, legislation require organizations to have formal training programs in place. This includes…

A company that sells and services car music systems has surveyed residents of the local area surrounding the store as a way to expand their business. They handed out cards at a busy intersection near the store over a two-weekend time period. After a month, they have received 200 responses out of 950 they distributed. The results of this survey will likely be ineffective because a handing out postcards is not a legitimate survey method handing out postcards is not a legitimate survey method b the sample of people may not be the store’s appropriate target the sample of people may not be the store’s appropriate target c not enough people responded not enough people responded D participants did not get a reward for responding
Analyse the issues described below using root cause analysis techniques. A travel agency has recently lost several medium-sized and large corporate customers due to complaints about poor customer service. The management team of the travel agency decided to appoint a team of analysts to address this problem. The team gathered data by conducting interviews and surveys with current and past corporate customers and gathering customer feedback data that the travel agency has recorded over time. About 2% of customers complained about errors made in their bookings. On one occasion, a customer requested a change to a flight booking. The travel agent wrote an e-mail to the customer suggesting that the change had been made and attached a modified travel itinerary. However, it later turned out that the flight reservation system had not confirmed the modified booking. As a result, the customer was not allowed to board the flight, leading to a series of severe inconveniences for the customer.…
Background: Data about the frequency of adverse events related to inappropriate care in hospitals come from studies of medical records as if they represented a true record of adverse events. In a prospective, observational design we analyzed discussion of adverse events during the care of all patients admitted to three units of a large, urban teaching hospital affiliated to a university medical school. Discussion took place during routine clinical meetings. We undertook the study to enhance understanding of the incidence and scope of adverse events as a basis for preventing themMethods: Ethnographers trained in qualitative observational research attended dayshift, weekday, regularly scheduled attending rounds, residents' work rounds, nursing shift changes, case conferences, and other scheduled meetings in three study units as well as various departmental and section meetings. They recorded all adverse events during patient care discussed at these meetings and developed a classification…
Experimental Study: In the experimental study, the researcher would first identify a sample population of individuals who are willing to participate in the study. The participants would be randomly assigned to two groups: intervention vs. control. The intervention group would consume a specific amount of fried food each day, while the control group would not consume any fried food. Both groups would undergo testing to measure cardiovascular health. In this study, the independent variable is fried food consumption, which is measured by recording the amount and type of fried food consumed by the intervention group. Cardiovascular health would be the dependent variable. The research would be conducted as a randomized controlled trial, a type of experimental study. The study could last several weeks or months, and participants would be closely monitored for changes in their cardiovascular health. Following the intervention, both groups would be subjected to post-intervention testing to…
