Whether in your life as a student or as a professional in the workplace, your life is filled with learning opportunities. With the material we've covered in the last five weeks in mind propose a study that represents points of comparison that can be tested. You can compare performance of a sample with that of a population, compare two samples, or the probability of an outcome using the binomial or Poisson distributions. These should be realistic tests/comparisons/probabilities. Though you do not need to compute the values to reach a conclusion, the study should be relevant and feasible. Full credit will involve 5 items:

Null and alternative hypotheses

Level of significance

Test statistic

Decision rule

A constructive comment on a colleague's proposed study. This comment should be (1) helpful and (2) more than just encouragement. It can address any of the four prior items.
