Note:As per HOMEWORKLIB RULES 4 bits
enough.Due to little confussion about d,e bits so
i couldn't solved.If you want to answer for d,e bits please post it
separately.
Thank you.

A control chart is used for monitoring a process meanl (X) that is normally distributed with a mean of μ and a standard deviation of σχ , and the sample size is n-5. А 3-sigma limit (μ ±30% ) is used as control limits. Two decision rules are given here. Rule 1: If one or more of the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is out of...

A control chart is used for monitoring a process mean ( 7 ) that is normally distributed with a mean of u and a standard deviation of o, and the sample size is n = 5. A 3-sigma limit (u +30z) is used as control limits. Two decision rules are given here. Rule 1: If one or more of the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is...

Control charts are to be kept on the thickness measurements for a process that rolls 10-gage copper sheets. The current specification in the sheets is 0.1360+0.0020 inch. After collecting 25 samples of n 5 measurements at approximately half-hour intervals, the data were used to determine Σ L:3.421 inches and R.-0.044 inches, with i1 to 25. Assume that the quality...
