he Vice President of marketing brought to the attention of sales managers the fact that most of the company's manufacturer representatives contacted clients and maintained client relationship in a disorganized haphazard way. The sales manager brought the reps in for a three day seminar and training session on how to use an organizer to schedule visit le and recall pertinent information about each client more effectively. Sales reps were taught how to schedule visits most efficiently to maximize their efforts. Sales managers were given data on the number of site visits by sales reps on a randomly selected day both before and after the seminar. Use the following data to test alpha =5% whether significantly more site visits were made post seminar. Assume the differences in the number of site visits are normally distributed Rep Before After 1. 2. 4 2. 4. 5 3. 1. 3 4. 3. 3 5. 4. 3 6. 2. 5 7. 2. 6 8. 3. 4 9. 1. 5 also calculate the 95% confidence interval for the difference in the number of site visits Please find: Confidence interval for the differences in the sales visits (Z, t, x^2 or F) at confidence interval = ? % left critical value right critical value upper confidence level lower confidence level
