Answer 1

SOLUTION

1) C is correct

Both common cause and special cause (Because two points lies outside the upper control limit

2) Option A is correct

With in variation basically an estimate of short term variation calculating an average range

3)Option C is correct

Overall variation is estimate of long term variation calculating the estimate of standard deviation based on all samples put together

4) True capability analysis make sense

5) It is false because value of Cp=0.35 process is not capable

6) it is false process is not centered on target

7) yes it is normal distribution it is true

8) false it has only 2 special cause bariation

9) True

10) true
