A study wаs cоnducted in 2023 tо try аnd determine the аverage cоmmute time for Americans. This data was based on commute times from across the nation. A researcher wanted to see if this data accurately reflected the commute times for drivers in her county so she decided to randomly sample 3000 workers from her county and record their commute times. The data is presented in the table below. Use this information to answer this question.    Commute Times Commute Times Frequency Relative Frequency Cumulative Frequency Cumulative Relative Frequency No Commute 825 27.5% 825 27.5% Less than 15 Minutes A 32% C 59.5% 15 - 29 Minutes 615 20.5% 2400 D 30 - 59 Minutes 495 B 2895 96.5% 60 - 119 Minutes 75 2.5% 2970 99% 120 Minutes or More 30 1% 3000 100%   Based on the table above, identify the four missing values of A, B, C, and D. Make sure clearly label which number corresponds to each letter and make sure to show your work as to how you arrived at your answer. Simply writing the answers will not earn full-credit on this problem.
