![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.
