With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is accepted if every item in the sample is okay. The ABC Electronics Company has just manufactured 1950 write-rewrite CDs, and 50 are defective. If 6 of these CDs are randomly selected for testing, what is the probability that the entire batch will be accepted?

With one method of a procedure called acceptance sampling, a
sample of items is randomly selected without replacement and the
entire batch is accepted if every item in the sample is okay. A
company has just manufactured 967 CDs, and 88 are defective. If 3
of these CDs are randomly selcted for testing, what is the
probability that the entire batch will be accepted? Does this
outcome suggest that the entire batch consists of good CDs? Why or
Why not?...

With one method of a procedure called acceptance sampling, a
sample of items is randomly selected without replacement and the
entire batch is rejected if there is at least one defective unit.
The ABCD Electronics Company has just manufactured 4500
write-rewrite CDs, and 150 are defective. If 4 of these CDs are
randomly selected and tested, what is the probability that the
entire batch will be rejected? Report the answer as a percent with
one decimal place accuracy. (You need...

The list of individuals from which a sample is actually selected
is called the sampling frame. Ideally, the sampling frame should
list every individual in the population, but in practice this is
often difficult. A sampling frame that leaves out part of the
population is a common source of undercoverage. In the following
questions select all choices that apply; to receive credit for the
question you must select all the correct choices and only the
correct choices.

Thirty-three items are randomly selected from a population of
350 items. The sample mean is 32, and the sample standard deviation
6. Develop a 90% confidence interval for the population mean.

Thirty-four items are randomly selected from a population of 260
items. The sample mean is 33, and the sample standard deviation 6.

In the table below are selected values for the OC curve for the
acceptance sampling plan n = 210, c = 6. Upon failed inspection,
defective items are replaced. Calculate the AOQ for each data
point. (You may assume that the population is much larger than the
sample.) Plot the AOQ curve. At approximately what population
defective rate is the AOQ at its worst? Explain how this happens.
How well does this plan meet the specifications of AQL = 0.015,...

numbers, what sampling method is used?
If the psychologist first takes all the women, and randomly
selects 51 of them by randomly drawing ID numbers. Then, she takes
all the men and randomly selects 51 of them by randomly drawing ID
numbers. What sampling technique did she use?
When a population is divided into subgroups with similar characteristics and then a sample is obtained, this method is called ________ sampling.
