Sampling Distributions

When the orig pop is not normal, the sampling dist of the sample mean can only be estimated if the _____ is 30 or more.

Once we have all possible, (or just a lot), of samples, we then find the _____________ of each sample.

The point of finding the sampling distribution of x-bar is to calculate _____________ about x-bar.

A __________ is a characteristic of a population.

Suppose the orig pop is not normal and sample size is 18, to calculate probabilities for x-bar we must __________

A ________ is a characteristic of a sample.

To find the ___________ of the distribution of sample means we take the standard deviation of all of them.

To find the sampling distribution of the sample means we must make a graph to find the ____________ of the distribution.

When standard deviation of the pop is unknown and sample size is small, we ________ to find the probability for x-bar.

Finding probabilities for x-bar is the __________ as finding probabilities for the sample mean.

The t-distribution is used to find probabilities for x-bar when the _________ of the orginal population is unknown.

The sample mean is a ____________.

To find the sampling distribution of a statistic, we would first take all possible ____________ from a population.

To find the ___________ of the distribution of sample means, we average them.

The t-distribution is very similar to the __________ distribution.

When a population is normal, the sampling distribution of the sample mean is _____________.
