Find the probability and interpret the results. If convenient, use technology to find the probability. During a certain week the mean price of gasoline was $2.716 per gallon. A random sample of 38 gas stations is drawn from this population. What is the probability that the mean price for the sample was between $2.697 and $2.715 that week? Assume sigma= $0.049.

1. What are the expected returns and standard deviations for stocks A and B?
2. What is the correlation coefficient between the two stocks?
3. Suppose the risk-free rate is 2%. What is the optimal risky portfolio, its expected return and its standard deviation?
4. Suppose that stocks A and B had the expected return and standard deviations as you calculated in question 1, while being perfectly negatively correlated. Again, assume the risk-free rate is 2%. Describe the global minimum variance portfolio in this case (that is, the proportions (wE, wD), the expected return and standard deviation).
