Reference no: EM13120089

Here are heart rates for a sample of 30 students before and after a class break. At α = .05, was there a significant difference 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) Estimate the p-value and interpret it. HeartRate
