Question: 8. A machining operation requires close tolerances on a certain part for automobile engines. The current specification for this measurement is 3.0 cm +- .001.

8. A machining operation requires close tolerances on a certain part for automobile engines. The current specification for this measurement is 3.0 cm +- .001. The quality control procedure is to take a sample of 4 units and measure each of the parts. On the basis of past samples of size 4, x-double bar = 3.0 and R-bar = .0020

a) Construct average and range charts for this part.

b) On the basis of the following data, is the process in control?

(Sample 1: X bar: 3.005, R: 0.0024)

(Sample 2: X-Bar: 2.9904, R:0.0031)

(Sample 3: X Bar: 3.001, R:0.001)

(Sample 4: X-Bar: 3.0015, R: 0.004)

(Sample 5: X-Bar:3.0008, R: 0.001)

c) Is the process creating output outside its specifications?
