a concerted effort to increase participation by the gender with fewer suggestions in each region and perhaps make an attempt to change corporate culture so that regional tendencies do not effect the employee suggestion program. 3 According to sources, Foot Locker has a 19.4% share of the sneaker market. Foot Locker believes that it holds a higher share of the market in the U.S. West. To test this notion, Foot Locker hires a market research company that randomly samples 1,000 people in the U.S. West who have just purchased new sneakers. Of these, 230 have purchased their sneakers at Foot Locker. The hypotheses being tested are: H 0 : p = .194 H a : p > .194

Case Notes 33 The sample information is: n = 1,000 x = 230 1000 230 ˆ = p = .230 Let alpha be .01. Chapter 9 techniques can be used to analyze these data. However, the chi-square goodness-of-fit can also be used. Using the .194 as the expected proportion and .230 as the observed proportion, a 2x2 table can be set up and analyzed using the chi-square goodness-of-fit. The observed frequency is calculated by taking .194 of 1,000 (the market share that Foot Locker holds nationally). f e f o e e o f f f 2 ) ( - Foot Locker 194 230 6.6804 Other Store 806 770 1.6079 The resulting observed chi-square is 8.2884. With 1 degree of freedom, and an α = .01, the critical chi-square value is 6.6349. The decision is to reject the null hypothesis. This indicates that proportion of the market share in the west is significantly higher than in other locales. Perhaps Foot Locker ought to study the clientele, the stores, the sales people, and the sale methods to determine why they are doing better in the West and attempt to implement things that they learn in other locales.
Case Notes 34 Chapter 13 Delta Wire Uses Training as a Weapon 1. Shown below is MINITAB output for correlation and regression analysis for the education and sick day data. The correlation between hours of education and number of sick days is a relatively strong negative correlation. This indicates that the more hours of education received, the fewer the sick days. There may be several reasons for this. One explanation may be that as workers participate in an educational process about their work, they become more interested in what they are doing because they understand more about it and can see more potential. If the training is interesting, they may look forward to the time in the classroom. In addition, they may feel more a part of the team by having been included in training and feel more self worth for being selected for the training.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
