90 adults with gum disease were asked the number of times per week they used to floss before their diagnoses. The (incomplete) results are shown below: # of times floss per week Frequency Relative Frequency Cumulative Frequency 0 0.1444 13 1 11 0.1222 24 2 9 0.1 33 3 13 4 9 0.1 55 5 15 0.1667 70 6 11 0.1222 81 7 9 0.1 90 a. Complete the table (Use 4 decimal places when applicable) b. What is the cumulative relative frequency for flossing 1 time per week? %
