Stock Market Performance: the Dow Jones Industrial Average (DJIA) and the Standard & Poor's 500 (S & P 500) indexes are used as measures of the overall movement in the Stock market. The DJIA is based on the price movements of 30 large companies; the S & P 500 is an index composed of 500 stocks. Some say the S & P 500is a better measure of the stock market performance because it is broad-based. The closing price for the DJIA and the S & P for 15 weeks, of a previous year follow (Barrow's website).

a. Develop a scatter diagram with DJIA as the independent variable.

b. Develop the estimated regression equation.

c. Test for a significant relationship.

d. Did the estimated regression equation provide a good fit? Explain.

e. Suppose that the closing price for DJIA is 13,500. Predict the closing for the S & P 500.

f. Should we be concerned that the DJIA value of 13,500 used to predict the S & P 500 value in part (e) is beyond the range of the data used to develop the estimated regression equation?

2 (a) Suppose you start with one Red and one Black ball in a bag. You draw a ball at random from the bag repeatedly and look at its colour each time. After each successive draw, you double the number of Red balls and triple the number of Black balls in the bag before the next draw (eg. on the third draw there will be 4 Red and 9 Black balls in the bag). Explain why you will draw only finitely many Red balls in total with probability 1. [3 marks]

(b) In a modified game, suppose instead that for before the nth draw, you first make an n by n square arrangement of balls where the perimeter balls are all Red and any interior balls are Black ball. Thus, on the second draw there are 4 Red and 0 Black in the bag (22 in total), on the third draw there are 8 Red and 1 Black in the bag (32 in total), on the fourth there are 12 Red and 4 Black in the bag (42 in total), and so on. How many Red and Black balls will there be on the nth draw? Will you still draw only finitely many red balls? Explain your answer. [4 marks]

Observational studies have suggested that vitamin E reduces the risk of heart disease. Careful experiments, however, showed that vitamin E has no effect. According to a commentary in the Journal of the American Medical Association: Vitamin E enters the category of therapies that were promising in epidemiologic and observational studies, but failed to deliver in adequately powered randomized controlled trials. As in other studies, the “healthy user’’ bias must be considered; i.e., the healthy lifestyle behaviors that characterize individuals who care enough about their health to take various supplements are actually responsible for the better health, but this is minimized with the rigorous trial design.

Explain, by describing lurking variables, why observational studies suggest that Vitamin E therapy reduces the risk of heart disease. Note that a randomized controlled trial is a type of experiment.
