Answer #1

Answer: 0.0308

Explanation:

Sample size, n= 50

Number of samples= 100

Total number of items= number of samples*sample size= 100*50= 5000

Fraction defective, p= number of defects from all samples/ total number of items across all samples

= 250/5000 =0.05

Standard deviation= \sqrt{\frac{p(1-p)}{n}}

= \sqrt{\frac{0.05(1-0.05)}{50}}

= 0.0308

    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...

    1 - Almost all processes, regardless on whether they are goods or services, exhibit some type of variation in their output. For example, a box of cereal may say that it contains 16 ounces, but in reality, it may be a little bit more, or a little bit less. The machine pouring the cereal into the box may not be adjusted properly, and it may only put 15.8 ounces in each box, on the average. This would be considered an...
