Answer:
the mean of the entire class is approximately 64.74.
Explanation:
To find the mean of the entire class, we'll calculate the overall average by considering the total number of students and their average scores.
Total number of students = 25 (females) + 70 (males) = 95 students
Total score of females = 25 (females) * 50 (average score) = 1250
Total score of males = 70 (males) * 70 (average score) = 4900
Total score of the entire class = 1250 (females' total score) + 4900 (males' total score) = 6150
Mean of the entire class = Total score of the entire class / Total number of students = 6150 / 95 ≈ 64.74
So, the mean of the entire class is approximately 64.74.
