Question

Quizplus · Accepted Answer

The weighted mean salary depends on the distribution of people across the three education levels. Without knowing the specific distribution, we cannot calculate the exact weighted mean. However, if there are equal numbers of people in each group, the weighted mean would indeed be $60,000. If the distribution is unequal, the weighted mean could be less or more than $60,000. Since the question does not specify the distribution, the most accurate answer is that it could be less than $60,000, assuming a distribution that does not equally weight the higher salaries.
