Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good baromet 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 assu that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day. A sample of 73 stocks traded on the NYSE that day showed that 14 went up. You are conducting a study to see if the proportion of stocks that went up is less than 0.3. You use a significance level of 0.005
