Consider this data set listing the number of service hours completed by 24 students. [34, 38, 39, 41, 42, 46, 48, 49, 52, 61, 62, 63, 37, 38, 41, 41, 46, 47, 49, 51, 61, 61, 62, 64] a. Create a histogram with bins of size 10. (Don’t forget to label your graph.) b. For the same data, rating categories were created based on number of service hours completed. Students who completed less than 38 service hours were rated as “poor,” at least 38 but less than 47 hours were “average,” at least 47 but less than 57 were “good,” and students with at least 57 hours were “excellent.” Complete the table below by finding the frequency and relative frequency of students in each rating category. Round relative frequency to one-tenth of a percent. [34, 38, 39, 41, 42, 46, 48, 49, 52, 61, 62, 63, 37, 38, 41, 41, 46, 47, 49, 51, 61, 61, 62, 64] Rating # of Students % of Students Poor Average Good Excellent c. Create a bar graph for the student service rating data.
