In-Class Exercise - Cpk Problem Design specifications require that a key dimension on a product measure 110 + 13 units. A process being considered for producing this product has with a mean of 110 units and a standard deviation of four units. a. What can you say (quantitatively) regarding the process capability? b. Suppose the process average shifts to 98 units. Calculate the new process capability. c. What can you say about the process after the shift? Approximately what percentage...

The Acme Company manufactures large capacity Flash drives using two different manufacturing processes. The company is interested in determining if there is a significant difference in the average manufacturing time of the two processes. For Process #1, a sample of 28 items shows a sample mean of 9 minutes and a sample standard deviation of 3.5 minutes. For Process #2, a sample of 23 items shows a sample mean of 13 minutes and a sample standard deviation of 4.5 minutes....

Zip, Inc. manufactures Zip drives on two different manufacturing processes. Because the management of this company is interested in determining if process 1 takes less manufacturing time, they selected independent random samples from each process. The results of the samples are shown below. Process 1 Process 2 Sample size, n 12 22 Sample mean (in minutes) 58 64 sample standard deviation, s 9 25 a. State the null and alternative hypotheses. b. Determine the degrees of freedom for the...

QUESTION 25 (10 points) ‐ Process Capability Indexes A ball bearing design for wheel assemblies used in giant mining dump trucks requires the inner diameter to have a lower specification unit (LSL) of 1,097.50 mm and an upper specification unit (USL) of 1,102.50 mm. A simple random sample of 270 finished ball bearings, which were produced by an approximately normally distributed process, has the sample average of 1101.20 mm and the sample standard deviation of 0.60 mm. A too small...
