6. A fraction nonconforming chart has center linep = 0.10, UCL=0.20, and LCL=0.0a). Assuming a 3-sigma chart is used, what is the sample size for the control chart for p.b). Use the Poisson approximation to the binomial to find the probability of a Type I error a.c). Use the Poisson approximation to find the Type II error if the actual fraction nonconforming p = 0.15e). If it is desired that the LCL should not be less than 0.02, what sample size n will guarantee thisvalue of the LCL. What is the corresponding value for UCL?

The records of a light bulb manufacturer show that, when the manufacturing machinery is working correctly, the defect rate (due to imperfections in the material used) is 1%. The manufacturer's control department periodically tests samples of the bulbs, and when 1.25% or more are defective, they call repair technicians for service. The control department is going to take a random sample of 4400 light bulbs. Let p be the proportion of defective light bulbs in the sample assuming the machinery is working correctly. A) find the mean of p b)find the standard deviation of p c)Compute an approximation for P≥p0.0125, which is the probability that, assuming the machinery is working correctly, the repair technicians will be called. Round your answer to four decimal places.
