Problem 3 (35 pts.)

In a production process, parts are processed with a mean diameter of µ=100 mm and a standard deviation of σ=2 mm. assuming that a sample of size n=4 units would be taken for quality control process, answer the following questions.

1. Set up a control chart with 3sx control limits.

      UCL =

      CL =

      LCL =

1. What is probability of type I error for the control chart above.

Prob. (Type I Error, α) =

1. Determine the average run length and the average time to signal (assuming a sample is taken every 30 minutes) when the process is in control.

     ARL0 =

     ATS0 =

1. What is probability of type II error if the process mean shifts to 00 mm?

Prob. (Type II Error, β) =          

1. Determine the average run length and the average time to signal (assuming a sample is taken every 30 minutes) when the process mean shifts to 00 mm.

      ARL1 =

      ATS0 =

1. Set up a control chart with α=0.003 probability limits (Note: Find Zα/2 and use this as the number of sigma units you will be away from center line for upper and lower control limits)

UCL =

        LCL =

1. Plot the following points (mean diameter values of samples) on the control chart developed in (a) and determine if any point is out of control by the Western Electric Specify the point and the rule.

As quality control manager at a raisin manufacturing and packaging plant, you want to ensure that all the boxes of raisins you sell are comparable, with 35 raisins in  each box. In the plant, raisins are poured into boxes until the box reaches its sale  weight. To determine whether a similar number of raisins are poured into each box, you randomly sample 25 boxes about to leave the plant and count the number of raisins in each. You find the mean number of raisins in each box to be 33.2, with s = 2.43. Perform the 4 steps of hypothesis testing to determine whether the average number of raisins per box differs from the expected average 35. Use alpha of .05 and a two-tailed test. 

2NO (g) + 2Cl2 = 2NOCl2 (g) given: Kp = 65000, what is themolarity of NOCl2 when the system is at equilibrium given that thepressure of NOCl2 = 8.9atm, partial pressure of NO = 0.35atm, andpartial pressure of Cl2 = 0.10atm

``` State<MyApp> createState => _MyApp(); ``` Using the above code I get Error: A value of type '_MyApp' can't be returned from a function with return type 'State<MyApp>
How do I resolve this issue?

Using Flutter.
Originally my issue was _MyApp createState() => _MyApp(); but I got that Avoid using private types in public api. I was told to use this method -  to resolve that issue

Assume that the total expenditure of a consumer on two goods X and Y is birr 2000 and prices of good X and Y are birr 50 and birr 40 respectively. Then formulate his budget equation and sketch the graph. Please I need the answers and I couldn't see it in this website please help

A uniform bar of weight 30 N and length 4m passes over a prop and is supported in a horizontal position by a force of 10 N acting vertically upwards at the other end. Find the distance of the prop from the center of the bars.
