Answer the following questions for a single sampling plan with sample size n = 80 and c = 3 1. Draw the OC curve for the sampling plan, using the Poisson table distributed in class 2. If AQL = 2% and LTPD = 7%, what would be the producer's and consumer's risks associated with the sampling plan? 3. If the sampling plan is used to inspect a lot of 10,000 products with an average defective rate of 3%, what would be the average quality after inspection, assuming all the defectives will be replaced if detected?

please answer with perfect formula !!!!!

without formula answer should be down thumbs

1. Consider a single sampling plan with a lot size of 1500, sample size of 150, and acceptance number of 3. Construct the OC curve. If AQL is 0.05% (0.0005) nonconforming, and the LQL is 6% nonconforming, describe the protection offered by the plan at these quality levels. 2. Same thing at sample size of 200. 3. Construct the Outgoing Quality Curve for #1. What is the AOQL? 4. Construct the ATI curve for #1. If the process average nonconformance...

Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 52 bank accounts, we want to take a random sample of four accounts in order to learn about the population. How many different random samples of four accounts are possible?

The following sampling plan has been established in a company. A sample of size 2 if both items are good lot is accepted. Otherwise a second sample size 1 if that second sample item is good the otherwise the batch is rejected. a) Develop a probability tree diagram to list the possible outcomes of the first sample and the second sample. b) If the inspector receives a batch with 10% of damaged items, calculates the probability of accept that lot.

The following sampling plan has been established in a company. A size 2 sample is drawn if both items are ok the lot is accepted. Otherwise a second sample of size 1 is taken if that item from the second sample is ok the lot is accepted otherwise the lot is rejected. [5] a) Develop a probability tree diagram to list the possible results of the first sample and the second sample. [15] b) If the inspector receives a batch...

A single observation of a random variable (that is, a sample of size n = 1) having a geometric distribution is used to test the null hypothesis θ = θ0 against the alternative hypothesis θ = θ1 for θ1 < θ0. The null hypothesis is rejected if the observed value of the random variable is greater than or equal to some positive integer k. Find expressions for the probabilities of type I and type II errors.

Section 8.1 #38 A sample of size n = 80 is drawn from a normal population whose standard deviation is σ = 6.8. The sample mean is x̄ = 40.41. a. Construct a 90% confidence interval for μ. b. If the population were not approximately normal, would the confidence interval constructed in part (a) be valid? Explain
