The sampling distribution of (\hat{p}) (the sample proportion) describes the distribution of sample proportions obtained from repeated random samples of a given size from a population. It is approximately normal when the sample size is large enough, typically when both (np) and (n(1-p)) are greater than 5, where (p) is the population proportion and (n) is the sample size. The mean of this distribution is equal to the population proportion (p), and the standard deviation (standard error) is given by (\sqrt{\frac{p(1-p)}{n}}).
What else can I help you with?
True or False A sampling distribution is a probability distribution for a statistic?
The statement is true that a sampling distribution is a probability distribution for a statistic.
What distribution is a sampling distribution referring to?
A sampling distribution refers to the distribution from which data relating to a population follows. Information about the sampling distribution plus other information about the population can be inferred by appropriate analysis of samples taken from a distribution.
When the population standard deviation is known the sampling distribution is a?
normal distribution
How is sampling distribution used in the process of hypothesis testing?
Sampling distribution is crucial in hypothesis testing as it provides the distribution of a statistic, such as the sample mean, under the null hypothesis. By understanding the sampling distribution, researchers can determine the likelihood of obtaining their observed sample statistic if the null hypothesis is true. This allows for the calculation of p-values, which indicate the probability of observing the data given the null hypothesis. Ultimately, this helps in making informed decisions about whether to reject or fail to reject the null hypothesis.
What will the sampling distribution of the mean be if a population is normally distribution?
Also normally distributed.
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 is the mean of the sampling distribution equal to?
The mean of the sampling distribution is the population mean.

What is a sampling distribution?
The sampling distribution for a statistic is the distribution of the statistic across all possible samples of that specific size which can be drawn from the population.
What is the difference between a population distribution and sampling distribution?
Population distribution refers to the patterns that a population creates as they spread within an area. A sampling distribution is a representative, random sample of that population.
When the population standard deviation is known the sampling distribution is a?
normal distribution
What will the sampling distribution of the mean be if a population is normally distribution?
Also normally distributed.
When the population standard deviation is known the sampling distribution is known as what?
normal distribution

Why sampling needed?
Sampling is needed in order to determine the properties of a distribution or a population. Sampling allows the scientist to determine the variance in an estimate.
