- 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?Can you please answer this question and all of the sub problems and show all of the steps to the solutionThe following items represent the number of birds observed at a given feeder over the past several days. What is the mode number of birds to visit that feeder? 59, 46, 44, 46, 44, 28, 70, 85, 44, 13, 83, 9, 28 Round to 2 decimal places as needed

One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of ? = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 32 waves showed an average wave height of x = 17.3 feet. Previous studies of severe storms indicate that ? = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01.
