    Hey everyon i am having trouble with the following form my home work and i hope you can give some hints. can i assume that this is a noma distebrution so my alpha is equal to 1-99.7 ?

    (a) You work as a quality engineer for a cereal company. The company has just started a new quality improvement program. They want you to construct a control chart for the average weight of the boxed cereals. The scheme you devised is the following: collect 5 boxes of cereal every 15 minutes, take the average weight and plot that average on a control chart with 3-sigma control limits. You also decided to check the control chart every hour (every 4 samples) and conclude that the process is out-of-control if you have at least one point outside the control limits. What is the type I error for this rule?

    @noob2 The more details you provide, the more likely you are to get a response. What do YOU think you should do? Why or why not?Β The iSixSigma audience is helpful, but they like to see that someone is putting forth a good-faith effort; they are not here to do your work for you.
