QuestionA questionnaire was given to students in an introductory statistics class during the first week of the course. One question asked, "How stressed have you been in the last 2122 \frac{1}{2} weeks, on a scale of 0 to 10, with 0 being not at all stressed and 10 being as stressed as possible?" The students' responses are shown in the frequency distribution below. How many students were involved in the study?

Studdy Solution
Calculate the total number of students by summing the frequencies:
5+3+4+15+12+17+11+21+24+14+17=1435 + 3 + 4 + 15 + 12 + 17 + 11 + 21 + 24 + 14 + 17 = 143
The total number of students involved in the study is:
143 \boxed{143}
