The t-distribution is used when the exact value of the population standard deviation is known.

Statistics Week 8 and 9

The independence condition required for using the Central Limit Theorem can be satisfied if the data come from a random sampling process.

The t-distribution is bell-shaped like the normal distribution, but it has tails that are __?__ indicating that observations are more likely to fall beyond two standard deviations from the mean.

In a t-distribution, the degrees of freedom describe the __?__ of the t-distribution.

As sample size increases, the t-distribution approaches the standard normal distribution.

When using the t-distribution, the population standard deviation is used to calculate the sampling error (SE).

Paired data is data that has a special __?__ between data pairs.

When analyzing paired data, it&#039;s useful to consider the difference in outcome of each pair of observations.

When performing a t-test for a single mean with sample size 28, the degrees of freedom would be __?__.

ANOVA is a process that allows one to compare means across many groups.
