A railway promises to ship freight from Toronto to Vancouver in 9 days, but customers consider any time between 6 and 14 days to be acceptable. Last week an auditor examined a sample of 71 shipments and found their delivery time had a mean of 10.4 days and a standard deviation of 1.5 days. The auditor also found 4 shipments where the customer had been charged too much money. With respect to shipping time, calculate the potential Sigma score for the process.

Using traditional methods, it takes 101 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 100 students and observed that they had a mean of 102 hours. Assume the variance is known to be 16. A level of significance of 0.05 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.
The time to deliver packaged containers by a logistics company is found fromsamples of size 4.

An automatic machine is used to fill cans with coffee. The nominal weight of each can is 16.0 oz. The standard deviation of the fill weight is known to be 0.10 oz. Cans are automatically inspected, and all underfilled cans are rejected. The selling price of a can of coffee is $3. Underfilled cans can be sold for $1.75. The cost of the coffee $0.10 per ounce. Determine the optimum mean target level for the filling machine
Mr. Ferdinand is a well-known entrepreneur who sells fresh organic beef to persons in the localcommunity. Customers love the quality of meet that Mr. Ferdinand sells so they tend torecommend his product to other people. Recently, Mr. Ferdinand has been running out of beefto sell to his customers. One customer suggests to him that he must use past sales records toforecast demand for his beef so that he can meet his customers' demand.I. Using a numerical example, demonstrate to Mr. Ferdinand how he can use a three-week and a four-week weighted moving average to forecast demand for his beef.II. Show how Mr. Ferdinand can test the accuracy of his forecast. III. Explain to Mr. Ferdinand two ways in which he can benefit from doing a forecast for his beef.

Need help calculating the margin of error for the question below. 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?
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.
You are a food specialist in a company that specializes inrefrigerated delicacies, and one of your brands requires beingmaintained at a temperature of 5°C. You determine averagewater activity (aw) at this temperature to be 0.2. One day, you are informed that the cooling systems onone of the delivery trucks carrying your company’s productsmalfunctioned while en route to its destination and it would notbe fixed until the next delivery. The driver has informed you thatthe temperature in the delivery bay of the truck is averaging55°C. You estimate a heat of sorption (Q) of 19 kJ/mol. Calculate the water activity of the brand at this elevatedtemperature and comment on it’s integrity. Should the deliverystill push through? Or should the products be recalled anddisposed

Management of Mittel Rhein AG of Köln, Germany, would like to reduce the amount of time between when a customer places an order and when the order is shipped. For the first quarter of operations during the current year the following data were reported: Inspection time- 0.7 daysWait time (from order to start of production) -16.6 daysProcess time -2.7 daysMove time -1.3 daysQueue time- 4.5 daysRequired:1. Compute the throughput time. (Round your answer to 1 decimal place.) 2. Compute the manufacturing cycle efficiency (MCE) for the quarter. (Round your answer to the nearest whole percentage (i.e., 0.12 should be entered as 12).) 3. What percentage of the throughput time was spent in non–value-added activities?

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.
