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
When the population standard deviation is known the sampling distribution is known as what?
normal distribution
What will the sampling distribution of the mean be if a population is normally distribution?
Also normally distributed.
What is Construction of a sampling distribution from scratch is feasible when the population is?
Real
A sample of 24 observations is taken from a population that has 150 elements The sampling distribution of the mean is?

What is the sampling distribution of a sample of 24 observations is taken from a population that has 150 elements?
12
What is the mean of the sampling distribution equal to?
The mean of the sampling distribution is the population mean.
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.
What distribution is a sampling distribution referring to?

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.
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
How do you investigate the distribution of sea snails?
By population sampling
When the population standard deviation is not known the sampling distribution is a?
If the samples are drawn frm a normal population, when the population standard deviation is unknown and estimated by the sample standard deviation, the sampling distribution of the sample means follow a t-distribution.
When a population distribution is right skewed is the sampling distribution normal?
No, as you said it is right skewed.
