SUMMARY
The mean score of a class of 30 students is 78, with 19 male students averaging 68. To find the mean score of the 11 female students, the equation .78 = (19/30)*.68 + (11/30)*x was established. Solving for x reveals that the mean score for the female students is 92. This calculation confirms the importance of weighted averages in determining group scores.
