IMPORTANT: Be sure you change the population statistic in the Test Statistic formula to reflect what you put in Ho and Ha.

The work below uses made-up data. Remember that the values you use in your hypotheses are up to you. You can compare your population parameters to any value; just remember that the sample statistic must agree with your alternate h We always try to reject the null hypothesis; that means we must have evidence (via the sample statistic) that the alternate hypothes Click in the cell to see the formula used.
