#1. a)

Construct the appropriate control chart for the 11 observations, and determine if the process is in control using two sigma limits. No. of defects per unit for the observations are: 4, 1, 8, 10, 4, 6, 10, 10, 1, 6, 6.

a. Under control

b. 4 observations out of control

c. 2 observations out of control

d. 3 observations out of control

Six samples of five observations each have been taken for a process. The sample means and ranges computed (in minutes) are, (mean, range): (4.11, 0.75), (4.14, 0.79), (4.01, 0.5), (3.6, 0.75), (3.88, 0.55), and (3.9, 0.68). Compute the upper control limit

a.2.561

b.4.262

c.4.329

d.2.955
