Note: Sample size calculations should be based on the way the data will be analyzed. But, even if more complex methods of analysis will be used ultimately, it is easier and usually sufficient to estimate the sample size assuming a simpler method of analysis, such as the t-test or two means or chi-square test of two proportions.

Randomly select a sample from the inspection lot. Random number tables (see Appendix B. “Random Number Tables”) or a calculator that is able to generate random numbers may be used to identify the sample. If the packages for the sample are not randomly selected, the test results may not be statistically valid.

Feb 04, 2013 · The standard deviation of a sample varies from sample to sample. This is not the case for sigma. We must use the T table for a T-test because the sample standard deviation varies. For a T-test, we must also determine the degrees of freedom. For a single-sample test, the degrees of freedom equals the sample size minus one . Example:

In a pre-test (While) loop, the condition is a continuing condition (Keep doing this loop While X is less than 10). It is written so that if the result of the condition is true, the loop recycles. In a post-test loop (Repeat), the condition is an exit condition (Repeat this loop until X is greater than or equal to 10).
