A researcher wants to study the academic performance of urban secondary schools in his county. He decides to measure each school's academic performance by collecting data on the percentage of students passing at least one Advanced Placement (AP) exam. The following table shows each school with the percentage of students passing at least one AP exam. No. School 1 Booker T. Washington High School 2 Central Academy 3 Hsi Lai Academy 4 Racine High School 5 Springfield High School 6 Hebrew Academy 7 Immaculate Conception High School 8 Performing Arts High School 9 60 10 Buckhead Heights High School West Springfield Technical High School 11 Westwood Heights High School 22 12 Longwood Academy 13 Anderson Technical High School 14 Taylor Technical High School 15 Arborville High School 16 Inglewood Heights Academy 17 Robert Wood Johnson Health Academy 18 Metropolitan Community School 19 20 21 22 23 Salaam Learning Academy 24 Northside College Preparatory High School 25 Friends Academy Peralta High School Grover Cleveland High School Lowell High School Danville High School Table1 Academic Performance (Percentage of students passing at least one AP exam) 3 18 23 29 34 37 39 47 51 53 58 64 67 68 72 75 77 78 81 82 85 87 91 92 98 These scores would be easier to visualize and interpret if they were graphed as a histogram. To do that, we first need to group them into class intervals and present them as a frequency distribution of grouped scores.

Table 2 divides the range of these 25 schools' academic performance into ten intervals. Based on the information provided in Table 1, use the dropdown menus to fill in the rest of Table 2 and complete the remainder of the problem. Note that the scores are listed in lowest to highest order. Table 2 Class Interval (Percentage of students passing at least one AP exam) 90-99 NUMBER OF SCHOOLS 50 In the frequency distribution table for the interval of 50-59, the real lower limit is 0 17 80-89 70-79 60-69 50-59 40-49 30-39 20-29 10-19 Now complete the following histogram. (Hint: Use a different orange rectangle for each class interval.) 0 0-9 Total (N) 10 f 3 4 20 30 40 50 60 70 ACADEMIC PERFORMANCE 2 1 1 → 80 90 100 and the real upper limit is ?
