Consider the following sample data of X and Y:
a. Regress Y against X without any constraints. What is the regression equation? Predict Y when X = 10.
b. Force the regression line through the origin. What is the new regression equation? Predict Y when X 10 with this equation.
c. Force the regression line to go through the point (5, 13). What is the new regression line? What is the new regression equation? Predict Y when X = 10 with this equation.
d. Regress Y against X with the constraint that the slope must be less than or equal to 2. What is the new regression equation? Predict Y when X = 10 with this equation.
Assume a population standard deviation of 350 kilowatt hours. Determine the standard error of the mean. With a 0.95 probability, determine the margin of error or standard error.

Each stated characteristic is a sample estimate. The 95% confidence intervals are [0.07 to 0.09] for PD, [$160,000 to $200,000] for EAD, The expected loss becomes the interval
What is the population mean? What is the best estimate of that value?
Suppose that a random variable X has a Binomial distribution with parameters n and p. Find E[(1/3)^X].
