What assumption is necessary to use the statistics for sampling with replacement?
Give two reasons why statistical methods tend to be based on the assumption that sampling is conducted with replacement, instead of without replacement.
In sampling theory,how many statistics we use to have an idea about population ?
Why does the bootstrap method require sampling with replacement? What would happen if bootstrap resampling was used, but the samples were without replacement?
Sampling technique: Pick a sampling technique discussed in the textbook-Business Statistics. In your own language, explain the process of applying this method, in what situation it can be used, and its strengths/weaknesses. Give an example of where you can use this method in your work of life: specify the population, sampling technique, and sample.

With one method of acceptance sampling, a sample of items is selected without replacement, and the entire batch is rejected if there is at least one defect. The Newport Gauge Company has just manufactured a batch of aircraft altimeters, and 3% are defective. If the batch contains 400 altimeters and 2 of them are selected without replacement for testing, what is the probability that the entire batch will be rejected?
A sampling distribution is Multiple Choice based on the assumption that the null hypothesis is correct. a probability distribution. specified by the null hypothesis. All answer choices are correct.
Suppose we performed the experiment with replacement: each time sampling a ball we would return it back. What would then be the distribution of X?
