It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

![QUESTION 41
An investor has decided to form a portfolio by putting 45% of his money into Google's stock and the remaining money into Apple's
stock. The investor assumes that the expected returns will be 12% on Google and 20% on Apple, and that the standard deviations
will be 0.10 and 0.20, respectively. What is the expected (mean) return on the portfolio?
OE [Return on portfolio] = 0.4160
O E [Return on portfolio] = 0.1560
O E [Return on portfolio] = 0.1640
OE [Return on portfolio] = 0.6140](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fce5febb7-d3d7-4c2f-8983-ba36bb85d089%2Ff69175ac-669b-4af8-859b-787ed2a268ed%2Fphykd2s_processed.jpeg&w=3840&q=75)
