Question: In exercise An inspector wants to use a variables sampling
An inspector wants to use a variables sampling plan with an AQL of 1.5%. Lots are of size 7,000 and the standard deviation is unknown. Find a sampling plan using Procedure 1 from MIL STD 414.
Answer to relevant QuestionsA lot of 500 items is submitted for inspection. Suppose that we wish to find a plan from MIL STD 414, using inspection level II. If the AQL is 4%, find the Procedure 1 sampling plan from the standard. a. Draw the type-A OC curve for the plan. b. Draw the type-B OC curve for this plan and compare it to the type-A OC curve found in part (a). c. Which curve is appropriate for this situation? A company uses a sample size equal to the square root of the lot size. If 1% or less of the items in the sample are defective, the lot is accepted; otherwise, it is rejected. Submitted lots vary in size from 1,000 to 5,000 ...An experiment was run to study the effect of two factors, time and temperature, on the inorganic impurity levels in paper pulp. The results of this experiment are shown in Table 8E.5: a. What type of experimental design has ...Find the standard error of the effects for the experiment in Exercise 8.4. Using the standard errors as a guide, what factors appear significant? In exercise
