The table shows information from a survey about the resting heart rate in beats per minute (bpm), for 200 college students who are in the marching band and who are not in the marching band. Beats/Minute below 80 bpmabove 80 bpm total in the marching band 56 28 84 not in the marching band 66 50 116 total 122 78 200 1. Create a two-way table that shows the relative frequency for each of the values in the table relative to all 200 people in the survey. 2. What is the probability that a person surveyed, selected at random, has a heart rate above 80 bpm or is in the marching band? 3. What is the probability that a person surveyed, selected at random, has a heart rate below 80 bpm and is not in the marching band?
