Hypothesis testing of a single mean and/or single proportion

This activity offers students direct experience with the 4 steps involved in hypothesis testing for the population proportion or the population mean:
 * 1) State the appropriate null and alternative hypotheses, Ho and Ha.
 * 2) Obtain a random sample, collect relevant data, and check whether the data meet the conditions under which the test can be used. If the conditions are met, summarize the data by a test statistic.
 * 3) Find the p-value of the test.
 * 4) Based on the p-value, decide whether or not the results are significant and draw your conclusions in context.
