A sum of 10 thousand dollars is invested at an annual rate R, i.e. the capital of the investor will be 10(1 + R) (in thousand dollars) after one year. The investor is hesitating to select stoke I or stoke II. The annual rate for stock I has a uniform distribution on (0.07, 0.19] and the annual rate for stoke II has a normal distribution N(0.12,0.022). Let X be the capital after one year if the investor has selected stoke I, and Y be the capital after one year if the investor has selected stoke II. Which of the following statements is true? Use the table of the cdf of standard normal distribution (click to see). Choose the option 'None among the others, if none of the others is true. If the investor hopes to obtain a capital of at least 11 thousand dollars after one year, it is better to choose stok None among the others The variance of X is 1.12 if the investor hopes to obtain a capital of at least 11.5 thousand dollars after one year, it is better to choose stoke II The standard deviation of Y is 2
