Question
In columns F and G, calculate two random variables A and B, where A = 5X + 7Y and B = X – 2Y. Use the observations in X and Y to generate 50 observations each for A and for B. Calculate the following in Excel: 3. The observed sample mean and standard deviation for A. 4. The observed sample mean and standard deviation for B. 5. Use the sample standard deviations for X and Y (i.e., as if they were ox and oy) to calculate the (theoretical) expected standard deviations for A and B.
