QUESTION 5 30 points Save Answer You are tasked with a Process Selection Project. There are two Processes (A and B) that could potentially work for your application (cutting tubing to a specified length). Sample data is provided by the two companies. Out of the 16 samples from Process A, you find an average of 34.27 inches and a standard deviation of 2.14 inches. Thirteen samples were taken from Process B improvement and had an average length of 41.81 inches and a standard deviation of 1.88 inches. a. Use a hypothesis test with a = 0.05 to determine if the population variances differ. b. Based on the results from part a, use the appropriate 90% confidence interval, to determine if the mean lengths from the two populations differ. c. Of the 16 samples from Process A, 2 are found to be defective. From Process B, 3 of the 13 samples are found to be defective. Conduct the appropriate hypothesis test to determine if the proportion of defective units from the two Processes differ. Use a = 0.01. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
