Suppose you have a company with four markets in four regions (eg China, United States, United Kingdom, Japan). The distribution of their sales is a normal distribution with a mean of 100 and a standard deviation of 0.5. What is the distribution of the total market, and what are the mean and standard deviations? If the four markets are not independent, what is the distribution?

    Are the inflation rates of the United States and the United Kingdom associated? If so, can we attempt to predict the U.S. inflation rate using the U.K. inflation rate? Suppose we fit the following simple linear regression model U.S. inflation rate i = β0 + β1(U.K. inflation rate)i + εi where the deviations εi were assumed to be independent and Normally distributed, with mean 0 and standard deviation σ. This model was fit to the data using the method of...
