...Business Research Methods, Part III Robert LaFond, Taylor Norman, Zephyr Scott, Vennita Watson QNT 561 May 13, 2013 Sripathi Nilkar Introduction As Ford Motor Company continues to seek ways to improve its current hybrid vehicles, the company will conduct a statistical analysis of the results of the questionnaires returned by its customers. Through this analysis, Ford Motor Company will be able to identify challenges that the company faces as well as the steps needed to reduce these challenges and improving both the company’s product and image. Statistical Analysis The results gathered from the questionnaire immensely helped Ford understand new aspects of an improved Hybrid vehicle. Subject 1 was the owner of a 2010 Ford Fusion Hybrid. Subject 1 has had 4 scheduled maintenance jobs performed on the car in the past year. On average, Subject 1 only drove 100 miles per week. Usually, scheduled maintenance is performed depending on the gas mileage of the car i.e. oil changes, tire rotation and balance, etc. Subject 1 took good care of their car over the past year, but still had two serious additional car problems. The 2010 Ford Fusion Hybrid costs Subject 1 on average $127.06 a week in gasoline. This customer is only satisfied at level 3. Being that this is only a three year old car, these problems point to inefficiencies with manufacturing. Both are costly for the owner to replace. Subject 2 is the owner of a 2012 Toyota Prius. Scheduled maintenance was performed...

...Business Research Methods: Part III Quinetta Coleman, Shonte Brockman, Leroy Ducasse, Courtney Misterek, Elliott Nelson, LaMonica Smiley QNT 561/Applied Business Research and Statistics Dr. Charlene Dunfee February 10, 2011 Abstract The research study was interested in determining whether extending the regular season of the National Football League (NFL) would be agreeable to NFL players and fans. The problem exists because the NFL owners are pushing for a season extension, but also want to consider how this will impact the players. Surveys were distributed to collect data for this important topic. It was concluded that neither fans nor players want to extend the season, and it is hopeful that these results will be provided and taken into consideration before the owners make a final decision. More of the Same Game Every year professional football keeps lovers of the game on edge, as fans watch a 16-game regular-season in anticipation of the big finale, the Super Bowl Championship. The football schedule consists of four pre-season games and 16 regular-season games. Roger S. Goodell, Commissioner of the NFL, has proposed shortening the pre-season by two games, thereby extending the regular season from 16 games to 18. The proposal by the commissioner has caused controversy between the NFL and the National Football League Players Association (NFLPA). With an extended season, probabilities exist that players will sustain more injuries and share less of the revenues...

...Business Research Project Part 5 Learning Team QNT 561 September 08, 2014 Business Statistical Analysis Scenario A GMC manager recently noticed that there is a production difference between the early shift and the late shift. The manager would like to determine why there is a difference in production between the shifts and asked for research on the issue. The research team came up with the following research question: Is there a reason for the different production levels between the day and evening shifts. Our team has come up with the following two null hypotheses: H0 - There is a significant difference in employee productivity between shifts due to worker age. Ha - There is no significant difference in employee productivity between shifts due to worker age. In order to accomplish this, we need to find the average number of errors along with the standard deviation. By doing so, we can set up a confidence interval to see if the late shift is truly doing better when it comes to quality. If they are, we can make the nomination that the manager has the late shift supervisors provide guidance to the early shift supervisors. There are various statistical reports that outsource the relationship between the independent variable(s) and the dependent variable. Here we will realize how GMC will translate the organization problem into a statistical problem, provide a solution to the problem statistically, and then translate the statistical solution...
