Hypothesis testing of a single mean--hrs/wk watching tv

This activity offers students direct experience with the 4 steps involved in hypothesis testing for 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.

Inference for the mean of a population
Use this activity for in-class collaborative group work.

Estimate for completion time: 45 minutes, with data collection occurring as students arrive for class.

Materials needed:
