- If a certifying agency raises the requirements for real estate agents, what sort of decision error is the agency protecting against?
- The desired sample size depends only the size of the population to be tested.
- The test statistic follows the formula of difference divided by variability.
- According to the central limit theorem, a population which is skewed to begin with will still be skewed when it is re-formed as a distribution of sample means.
- The critical value of t to determine statistical significance depends on the sample size.
- The one-sampleĀ
*t*-test differs from theĀ*z*-test in which way?

- The z- test requires an estimate of the population standard deviation.
- The mean of the distribution of sample means will have the same value as the mean of the distribution of individual scores upon which it is based.
- The independent t-test is based on which distribution?

- The standard error of the mean is actually the standard deviation of all of the means that make up the distribution of sample means.
