Formulate null and alternative hypotheses to test analysts, Macroeconomics

Assignment Help:

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.
