Sampling distribution are used to: a) Estimate the number of samples or surveys to make to obtain a specified confidence in a particular statistic. b) Determine the confidence interval and the margin of error of a particular statistic. c) Conduct a hypothesis test on a particular statistic. I note that common statistics are mean and variance. However, there are sampling distributions for many statistics, including proportion and coeficient of correlation. Hypothesis testing can be one tail or two tail, and there are different approaches.

In an SRS of size n what is true about the sampling distributions of p when the sample size n increases?
As n increases the sampling distribution of pˆ (p hat) becomes approximately normal.
What type of sampling is used to estimate the percentage of defects?
random sampling
Statement of sampling theorem?
sampling theorem is used to know about sample signal.
What is the difference between flat top sampling and natural sampling?
in flat top sampling the electronic circuit required for sampling are less complicated as compared to the one used in natural sampling, at demodulation of the sample it is very difficult to maintain the natural waveform of the natural sampling so flat top sampling can easily be demodulated.
When is purposive sampling used?
it is also used in political polling
The usual sampling distributionof the difference between means is a what?
There is no such thing as "the usual sampling distribution". Different distributions of the original random variables will give different distributions for the difference between their means.There is no such thing as "the usual sampling distribution".

How do engineers apply statistical distributions in measurements?
Engineers apply statistical distributions in measurements while sampling products. It is also used in obtaining estimates used for project proposals and project implementation.

Why is sampling with replacement used?
its not a sampeling

Why is random sampling used by pollsters?
They think that if they used the random sampling after people voted because they want to get a better view of who will be the next president.
What is systematic sampling use for?
In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work. It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed. It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.
When is purposive sampling used?
it is also used in political polling
What is meant by sampling in computer graphics?
Sampling is the key technique used to digitize analog information. For example, music CDs are produced by sampling live sound at frequent intervals and then digitizing each sample. The term sampling is also used to describe a similar process in digital photography.
What is the purpose of the sample proportion?
The sampling proportion may be used to scale up the results from a sample to that of the population. It is also used for designing stratified sampling.
