Show metadata from the gapminder dataframe assign ggplot(data = gapminder, mapping = aes(x = gdpPercap, y = lifeExp) to the variable 'p' find the structure of the p object. add geom.point() to the p object. Show p. replace geom.point() with geom.smooth(). Show p. return to geom.point and add geom.smooth(). Show p. add the linear element to the geom.smooth function. Show p. change the x axis scare to log10. Show p. try scale_y_log10(). Show p. change the method to gam from lm. Show p. replace scientific notation on the x axis with dollar signs identify the continent of each point with color. Show p. add labels to the plot. Show p. change the method to loess. Show p. use fill to change the appearace of lines, points, and the interior of the smoother's standard error ribbon. S thehow p. limit the figure size in R markdown to 8 x 5. save one of your plots in it's own file. experiment with saving files in different formats and different locations. map different attributes from gapminder to see what they look like. Show the result. Submit a Word document by Sunday at midnight with your screen shots of your work. Explain what each image is. Explain and interpret each visualization. Highlight your comments.

3. Using Beta. A stock with a beta of .8 has an expected rate of return of 12%. If the market return this year turns out to be 5 percentage points below expectations, what is your best guess as to the rate of return on the stock? (LO12-1) 4. Specific versus Market Risk. Figure 12.11 shows plots of monthly rates of return on three stocks versus the stock market index. (The plots are similar to those in Figure 12.2.) The beta and standard deviation of each stock are given beside its plot. (LO12-1) a. Which stock is safest for a diversified investor? b. Which stock is safest for an undiversified investor who puts all her funds in one of these stocks? c. Consider a portfolio with equal investments in each stock. What would this portfolio’s beta have been? d. Consider a well-diversified portfolio made up of stocks with the same beta as Intel. What are the beta and standard deviation of this portfolio’s return? The standard deviation of the markket portfolio’s return is 20%. e. What is the expected rate of return on each stock? Use the capital asset pricing model with a market risk premium of 8%. The risk-free rate of interest is 4%. 8. Portfolio Risk and Return. According to the CAPM, would the expected rate of return on a security with a beta less than zero be more or less than the risk-free interest rate? Why would investors invest in such a security? (Hint: Look back to the auto and gold example in Chapter 11.) (LO12-1) 9. Risk and Return. Suppose that the risk premium on stocks and other securities did, in fact, rise with total risk (i.e., the variability of returns) rather than just market risk. Explain how investors could exploit the situation to create portfolios with high expected rates of return but low levels of risk. (LO12-2) 14. Expected Returns. Consider the following two scenarios for the economy and the expected returns in each scenario for the market portfolio, an aggressive stock A, and a defensive stock D. (LO12-2) Rate of Return Scenario Market Aggressive Stock A Defensive Stock D Bust ?8% ?10% ?6% Boom 32 38 24 a. Find the beta of each stock. In what way is stock D defensive? b. If each scenario is equally likely, find the expected rate of return on the market portfolio and on each stock. c. If the T-bill rate is 4%, what does the CAPM say about the fair expected rate of return on the two stocks? d. Which stock seems to be a better buy on the basis of your answers to parts (a), (b), and (c)? 3. Using Beta. A stock with a beta of .8 has an expected rate of return of 12%.
