Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives 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).

b. A sample of 50 stocks traded on the NYSE that day showed that 24 went up. What is
your point estimate of the population proportion of stocks that went up?
c. Conduct your hypothesis test using α
α= .01 as the level of significance. What is your
conclusion?
