- Items are submitted for inspection in lots of size 1000 using the ANSI/ASQC Z1.4 standard. The general inspection level is level II, and AQL is 1% nonconforming for single sampling plans. Normal inspection is initiated at the start of lot 1. The inspection results for 10 consecutive lots are shown here:

In a factory you buy large lots of bolts that has an acceptable quality level of 5% and a rejectable quality level of 10%. When the lots arrive to the factory the quality is controlled using the following double sampling plan: 1st Sample: Pick 30 bolts at random a. If they are all conforming then accept the lot b. If there are 3 or more nonconforming then reject the lot c. Else take a second sample 2nd Sample: Pick 50...

Please answer broadly of the following 2 question: Question 1: One thousand lots of product, each consists of 20 items. Randomly take out 3 in a lot and reject the lot if nonconforming parts are found. At last, there are 850 lots out of the 1000 lots are accepted. Estimate the average quality level of these products. Question 2: When a company decides its purchasing policy, it has many choices, like multi-supplier or single supplier. Compare the two policies from...

The Excel file Room Inspection provides data for 100 room inspections at each of 25 hotels in a major chain. Management would like the proportion of nonconforming rooms to be less than 2%. Formulate a one-sample hypothesis test for a proportion and perform the calculations using the correct formulas and Excel functions, and compare your results with the One Sample Hypothesis Test Excel template to verify them.
