Shown below is a randomization dotplot for sample differences in student pulse rates during a quiz versus listening to a lecture. Use the randomization dotplot to answer the questions that follow: The randomization dotplot is based on 5000 simulated samples under the null hypothesis assumption that there is no difference in mean pulse rates during a quiz versus during a lecture. The alternative hypothesis is that the difference is greater than zero (or that the mean pulse rate is higher during a quiz).
