Recently Dave's Burgers has followed the lead of larger franchise restaurants likeBurger King, McDonald's, and Wendy's and constructed drive-through windows at all itslocations. However, instead of making Dave's Burgers more competitive, the drive-throughwindows have been a source of continual problems, and it has lost market share to its largercompetitors in almost all locations. To identify and correct the problems top management hasselected three of its restaurants (one in each state) as test sites and has implemented a TQMprogram at each of them. A quality team made up of employees, managers, and qualityspecialists from company headquarters, at the Charlotte, North Carolina, test restaurant usingtraditional TQM methods like Pareto charts, check sheets, fishbone diagrams, and processflowcharts.havedeterminedthattheprimaryproblemisslow.erraticserviceatthedrive-throughwindow. Studies showed that from the time a customer arrived at the window to the time theorder is received averages 2.6 minutes. To be competitive management believes service timeshould be reduced to at least 2.0 minutes and ideally 1.5 minutes.The Charlotte Dave's Burgersfranchiseimplementedanumberofproductionprocesschangestoimproveservicetime at thedrive-through window. It provided all employees with moretrainingacross all restaurant functions, improved the headset system, improved the equipment layout,developed clearer signs for customers, streamlined the menu, and initiated even-dollar (taxinclusive) pricing to speed the payment process. Most importantlythe restaurant installed large,visible electronic timers that showed how long a customer was at the window. This not onlyallowed the quality team to measure service speed but also provided employees with a constantreminder that a customer was waiting.

Average service time is observed as 2.6 minutes per customer at the drive-through window which…

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?
Accountants at the Tucson firm, Larry Youdelman,CPAs, believed that several traveling executives were submittingunusually high travel vouchers when they returned from businesstrips. First, they took a sample of 200 vo uchers submitted fromthe past year. Then they developed the following multiple regressionequation relating expected travel cost to number of days onthe road (x1) and distance traveled (x2) in miles:y = $90.00 + $48.50x1 + $.40x2The coefficient of correlation computed was .68.a) If Barba ra Downey returns from a 300-miJe trip that took herout of town for 5 days, what is the expected amount she shouldclaim as expenses?b) Downey submitted a reimbursement request for $685.

Kay and Micheal Passe publish what's Happening?--a biweekly newspaper to publicize local events. whats happening? has a few subscribers; it typically is sold at checkout stands. Much of the revenue comes from advertisers of garage sales and supermarket specials. In an effort to reduce costs associated with printing too many papers or delivering them to the wrong location, Micheal implemented a computerized system to collect sales data. Sales-counter scanners accurately record sales data for each location. Since the system was implemented, total sales volume has steadily declined. selling advertising space and maintainting shelf space at supermarkets are getting deifficult. Reduced revenue makes controlling costs all the more important. For each issue. Micheal caefully makes a forecast based on sales data collected at each location. Then he orders papers to be printed and distributed in quantities matching the forecast. Micheal's forecast refect a downward trend, which is present in the…

Athlete ages A sports reporter suggests that professional baseball players must, on average, be older than profes-sional football players, since football is a contact sport and players are more susceptible to concussions and seri-ous injuries (www.sports.yahoo.com). One player was selected at random from each team in both professionalbaseball (MLB) and professional football (NFL). Thedata are summarized below.To perform inference on these two samples, what condi-tions must be met? Are they? Explain. MLB NFLn 30 32y 27.5 26.16s 3.94 2.78
