Closing TechniquesThe effectiveness of closing techniques has been debated among sales strategists. Closing technique 1 is the most aggressive technique with closing technique 2 being moderately aggressive and closing technique 3 being a no-pressure technique. To determine the impact that each of the techniques has on developing a long term buying relationship, 60 purchasing executives, 20 per technique, were subjected to each of the closing techniques and then asked to rate their willingness to develop a long-term buying relationship with the salesperson. The rating scale ranges from 1 (not willing at all) to 9 (extremely willing). a. Perform the ANOVA on the data. Which pairs of sample means appear to be significantly different? b. Do the data provide sufficient evidence to conclude that the mean rating differs across the three closing techniques? Use a 5% significance level. c. Apply Tukey's multiple comparisons procedure using a 5% significance level. Does this agree with your response to part (a)? d. Do a "what if' analysis by adding 10 to all the ratings. What parts of the analysis does this change? e. Do a "what if' analysis by multiplying all the ratings by 10. What parts of the ANOVA table and multiple comparisons procedure change? Employee Morale StudyVariable description: Morale97: Morale of employee in 1997 Morale98: Morale of employee in 1998 Morale99: Morale of employee in 1999 The manager of a large factory is interested in determining if there has been a change in the morale of employees over the past three years. Thirty employees are randomly selected to provide a score between 1 and 10 indicating the morale level for each of the employees for each of the years 1997, 1998, and 1999. A score of 10 indicates the highest possible level of morale. a. Test the hypothesis that the mean morale score has not changed over the three years. Use a 5% significance level. b. Is there an effect due to blocks? Use a 5% significance level. c. Should a multiple comparisons procedure be performed to determine which years differ with respect to morale? Production AnalysisVariable description: ExpLevel: Low (1) or High (2) experience level of operatorSpeedA: Number of nonconforming items for speed level ASpeedB: Number of nonconforming items for speed level BSpeedC: Number of nonconforming items for speed level CSpeedD: Number of nonconforming items for speed level DA quality engineer believes that there are two factors affecting the number of nonconforming items produced by a machine. The first factor is the experience level of the operator denoted by 1 and 2 for low and high experience, repectively. The variables SpeedA, SpeedB, SpeedC and SpeedD are used to record the number of nonconforming items for four different machine speed levels. There are eight replicates for each of the factor level combinations.a)
