1. Simplified stock market Suppose there are three kinds of days: GOOD, GREAT, and ROTTEN. The following table gives the frequency of each of these types of days and the effect on the price of a certain stock on that day. Type of Day | Frequencey | Change in value---------------------------------------------GOOD | 60 % | +2GREAT | 10 % | +5ROTTEN | 30 % | -4 The type of a given day is independent of the type of any other day. Let X be the random variable giving the change in value of the stock after 1 day. a. What is the expected change in the stock price? (That is, find E(X)) b. Calculate Var(X). Note: Give your answer in decimal form, round to the nearest hundredths place.
We are making a historical study of the American economy from 1950 to 1980. Data on prices, the labor force, productivity, and the GNP were collected. Note in the following table that the CPI has a base period of 1967, employment is in millions of persons, and so on. A direct comparison, therefore, is not feasible. a. Using 1950 as the base period, make whatever calculations are necessary to compare the trend in the four series from 1950 to 1980. (Round your answers to 1 decimal place.) b. Interpret the results. (Round your answers to 1 decimal place.)
