Q1: This question is overall a mouthful. I couldn’t keep track of the incomes, percentages, and corporations. Tried to write it out multiple times and draw diagrams but it just confused me more. The correct answer is D.
Q2:
For this question, is there a way to find the difference between the means without calculating the mean for both and then subtracting, as that would be too time consuming? The correct answer is A.
Thanks in advance!!
