1. The problem asks for the total number of students involved in the study based on the frequency distribution of stress ratings. 2. The frequency distribution table lists stress ratings from 0 to 10 and their corresponding frequencies (number of students who gave each rating). 3. To find the total number of students, we sum all the frequencies: $$6 + 5 + 4 + 17 + 17 + 11 + 14 + 32 + 35 + 15 + 11$$ 4. Calculate the sum step-by-step: $$6 + 5 = 11$$ $$11 + 4 = 15$$ $$15 + 17 = 32$$ $$32 + 17 = 49$$ $$49 + 11 = 60$$ $$60 + 14 = 74$$ $$74 + 32 = 106$$ $$106 + 35 = 141$$ $$141 + 15 = 156$$ $$156 + 11 = 167$$ 5. Therefore, the total number of students involved in the study is 167. This means 167 students responded to the stress rating question in the survey.
