A process is operating with a mean of 2.7 meters and a standard deviation of .6. The customer has an upper specification of 3.9 and lower specification of 1.5. What is the estimated percent in spec?

A)5%

B)97.5%

C)95%

D)nearly 100%

Expert Solution

µ = 2.7

sd = 0.6

= P(-2 < Z < 2)

= 95% (because according to empirical rule area between two standard deviation is equal to 95%)

Option-C) 95%

A process has mean 11 and standard deviation 2.5. The process is monitored by taking samples of size 5 at regular intervals. The process is declared to be out of control if a point plots outside the 3σ control limits on a chart. 17a.) If the process mean shifts to 14, what is the average number of samples that will be drawn before the shift is detected on a X⎯⎯⎯X¯ chart? 17b.) An upward shift to what value will be...
