ID: 2924674 • Letter: T

Question

True or False. To create a simulation of the null distribution for a single mean, we resample with replacement from the original data set.

-----

Besides needing at least 20 observations in our sample, what else needs to be true about the sample distribution in order to meet the validity conditions for a one sample t-test when we don't have a symmetric distribution to begin with?

Question options:

Nothing as long as we have at least 10 successes and 10 failures.

   

The sample distribution must be symmetric.

The sample distribution should be strongly skewed.

The sample distribution should not be strongly skewed.
