Week 10:Two sample test difference of mean(z and t test)
The statistical techniques presented in this chapter are used when we are comparing two random samples. If the samples are significantly different, we conclude that the populations from which they were selected are different. This conclusion has a known probability of error, which is often set at 0.05.
