A manager is simulating the number of times a machine operator stops a machine to make adjustments. After careful study the manager found that the number of stops ranged from one to five per cycle and that each number of stops was equally likely. Using the random numbers 0.72 and 0.27 (in that order), determine how many stops for adjustments each of the next two cycles will have.

I show n=100, sigma = 1, and 95% prob equls a z score of 1.96 for z_alpha/2. Just having issues calcuating the Margin of Error value. The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took these 100 customers to check out was 3 minutes. It is known that the standard deviation of the population of checkout times is 1 minute. With a 0.95 probability, the sample mean will provide a margin of error of 0.196. If we wanted to cut this margin of error in half, how many customers would we need to include in our sample?
- John Patrick has recently been hired as controller of Valdosta Vinyl Company (VVC), a manufacturer of vinyl siding used in residential construction. VVC has been in the vinyl siding business for many years and is currently investigating ways to modernize its manufacturing process. At the first staff meeting, Patrick attended, Jack Kielshesky, chief engineer, presented a proposal for automating the Molding Department. Kielshesky recommended that the company purchase two robots that would have the capability of replacing the eight direct-labor employees in the department. The cost savings outlined in the proposal include the elimination of direct-labor cost in the Molding Department plus a reduction of manufacturing overhead cost in the department to zero because VVC charges manufacturing overhead on the basis of direct-labor dollars using a plantwide rate. The president of VVC was puzzled by Kielshesky's explanation: "This just doesn't make any sense.

- The relationship between study hours and exam score was estimated as below in a linear format. Exam score = 6.24 * Study hours + 54.72 (The p-value for the coefficient of Study hours is 0.04.) How can the relationship between exam score and study hours be interpreted? As a person studies 1 more hour, his or her exam score is expected to decrease by 6.24 points. As a person studies 1 more hour, his or her exam score is expected to increase by 6.24 points. There is no meaningful relationship between exam score and study hours from a statistical point of view.I used excel and got a 1.31 on this question, but my friend got another answer.Employees at Precision Engine Parts Company produce parts according to exact design specifications. The employees are paid according to a piece-rate system, wherein the faster they work and the more parts they produce, the greater their chances for monthly bonuses. Management suspects that this method of pay may contribute to an increased number of defective parts. A specific part requires a normal, standard time of 23 minutes to produce. The quality control manager has checked the actual average times to produce this part for 10 different employees during 20 days selected at random during the past month and determined the corresponding percentage of defective parts, as follows: Develop a linear regression model relating average production time to percentage defects to determine whether a relationship exists and the percentage of defective items that would be expected with a normal production time of 23 minutes.
