Formulate null and alternative hypotheses to test analysts, Macroeconomics

Assignment Help:

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) provides a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange
(NYSE) went up the same day.

c. Conduct your hypothesis test using ? = :01 as the level of significance. What is your conclusion?
