Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2017, 9 of the 30 stocks making up the DJIA increased in price. On the basis of this fact, a financial analyst claims we can assume that 62% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day. A sample of 93 stocks traded on the NYSE that day showed that 55 went up. You are conducting a study to see if the proportion of stocks that went up is significantly smaler than 62%. You use a significance level of a = 0.05. 1. For this study, we should use Select an answer v 2.
