• State the statistical hypotheses;
• State the statistical tests you choose to use. Be specific (how many population, right, left or two-tail, and why do you choose this test);
• State the decision rules;
• Perform the statistical tests in R or by hand;
• Report the results;
• State the statistical decision.

Perform the appropriate statistical tests and report the results of two different analyses:

1. Assume that the variances of the two groups are equal.
2. Assume that the variances of the two groups are unequal.
