a) Step 1: Identify the score range for a student who scored 85. A score of 85 falls within the range of 80-89. The student will be added to the bar representing scores from 80-89. b) Step 1: Identify the number of students in categories with scores less than 70. Scores less than 70 include the categories 50-59 and 60-69. • Students scoring 50-59: 6 • Students scoring 60-69: 5 Step 2: Sum the number of students in these categories. Total students = 6 + 5 = 11 11 students scored less than 70. c) Step 1: Determine the most popular category and its frequency. The most popular category is 70-79, with 8 students. Step 2: Calculate the target total frequency. One less than the most popular category is 8 - 1 = 7 students. Step 3: Find two categories whose frequencies sum to the target total of 7. • Category 50-59 has 6 students. • Category 80-89 has 1 student. 6 + 1 = 7 The two categories are 50-59 and 80-89.
