This discusses the key formulas used for calculating the t-procedures of a 2 sample test where the mean and standard deviation of the population are unknown. (part 1 of 2)

Here are a couple of different examples using the t-procedures for 2-sample problems. One calculates the confidence interval and the other determines whether the null hypothesis can be rejected based on the calculated p-value. Charts used in examples can be found at www.math.unb.ca or at medcalc.be (Part 2 of 2)

This is about 1 sample t-procedures. That is, inference calculations when the mean and standard deviation of the population are unknown.
