Dr. Arsham's Statistics Site. Some widely used applications of the popular statistical tables can be categorized as follows: Conditions for using this table: Test for randomness of the data is needed before using this table. Test for normality condition of the population distribution is also needed if the sample size is small, or it may not be possible to invoke the central limit theorem. Notes: As you know by now, in test of hypotheses concerning m, and construction of confidence interval for it, we start with s known, since the critical value (and the p-value) of the Z-Table distribution can be used. Considering the more realistic situations, when we don't know s, the T-Table is used.
In both cases, we need to verify the normality condition of the population's distribution; however, if the sample size n is very large, we can in fact switch back to Z-Table by virtue of the central limit theorem. Conditions for using this table: Test for randomness of the data is needed before using this table. Binomial Probability.
