Question 2:Consider again that the company making tires for bikes is concerned about the exact width ofits cyclocross tires. The company has a lower specification limit of 22.8 mm and an upperspecification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm.What is the probability that a tire will either be too wide or too narrow?

2) The specification for a Lindemann’s stainless steel chimney liner requires a thickness of 7.1 mm ± 0.1 mm. The firm’s quality analyst determines that the liner process operates at a mean thickness of 7.13 mm with the standard deviation of the process being 0.02 mm. a) Calculate the upper and the lower limits for the stainless steel chimney liner. b) Calculate the Cpand Cpkfor this process. Hint: Cp = (Upper Specification Limit – Lower Specification Limit)/6sigma Cpk = minimum of [(Upper Specification Limit – Xbar)/3sigma], [(Xbar – Lower Specification Limit)/3sigma]

A Brisbane warehouse buys pre-packed bulk bags of Bundaberg Sugar with an advertised mean weight of 20 kilograms. To determine the validity of the advertised claim, the warehouse manager took a random sample of 55 packets from the latest shipment and found an average weight of the packets of 20.011 kilograms. Bundaberg Sugar know, from analysing data over many years, that their 20kg bulk bag packing process results in a standard deviation of 45 grams. 1. State the direction of the alternative hypothesis used to test the advertised claim. Type the letters gt (greater than), ge (greater than or equal to), lt (less than), le (less than or equal to) or ne (not equal to) as appropriate in the box. 2. Use the tables in the text to determine the critical value used to conduct the test, assuming a 10% level of significance. If there are two critical values, state only the positive value. 3.
