    Here are heart rates for a sample of 30 students before and after a class break. At alpha =.05, was there a significant diffeence in the mean heart rate?
    (a) State the hypotheses.
    (b) State the decision rule and sketch it.
    (c) Find the test statistic
    (d) Make a decision.
    (e) Find the p-value and interpret it.
