Question 2
You want to determine the control lines for a “P” chart for quality control purposes. If the total number of defects from all samples is 560, the number of samples is 70 and the sample size is 80, what would be the standard deviation used in developing the control lines?
question 3
Assume a fixed cost for a process of $120,000. The variable cost to produce each unit of product is $35 and the selling price for the finished product is $50. What is the number of units that has to be produced and sold to break-even?

Binomial Distributions Given your statistical knowledge, you have been asked to assist the quality control manager of a local manufacturer in establishing and seeing that the factory conforms to standards set by management. The facility manufactures a new electronic toy. The factory can produce 1000 toys per day. Management has indicated that initially they will be satisfied if the defect rate is 3% or less. Since you can’t quality-test every toy produced, you suggest that a random sample of 40...

Smith and Johnson Industries has decided to use a p-Chart with 3-sigma control limits to monitor the proportion of defective galvanized pipes produced by their production process. The quality control manager randomly samples 150 galvanized pipes at 16 successively selected time periods and counts the number of defective galvanized pipes in the sample. Step 1 of 8: What is the Center Line of the control chart? Round your answer to three decimal places. Step 2 of 8: What value of...

Quality control A process starts out of statistical control but this is not known to the user. It will be stopped after T hr. Once a sample average falls outside the control limits, the process is stopped and investigated. It takes ta hours to find the assignable cause and repair the process at a cost of ca. Units produced under the presence of the assignable cause are assumed nonconforming. Cost of a nonconforming unit is cn. The process generates N...

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...
