• In a city with three high schools, all ninth graders took a standardized test with the following results: - Glenwood High School had a mean score of 78 with 269 ninth graders. - Central City High School had a mean score of 93 with 321 ninth graders. - Lincoln High School had a mean score of 66 with 161 ninth graders. The city's PR manager, who lacked a background in statistics, incorrectly claimed that the mean score for all ninth graders in the city was 79. To calculate the correct mean score for all ninth graders in the city, use the following formula: Mean = (Sum of all scores) / (Total number of ninth graders) Multiply the mean score by the number of ninth graders for each school to get the total score for that school. Then add up all the total scores and divide by the sum of all ninth graders: (78 * 269) + (93 * 321) + (66 * 161) = 20982 + 29853 + 10626 = 61461 Total number of ninth graders = 269 + 321 + 161 = 751 Mean score = 61461 / 751 ≈ 81.84 Thus, the mean score for all ninth graders in the city, rounded to two decimal places, is 81.84.
