Hi I want to explain this question to my classmates but my English is poor.

It will be grate if I can explain this question simply and fluently around 2 min ~ to 3 min with English sentence on it.

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) provides 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). 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. 1- Formulate null and alternative hypotheses to test the analysts claim. 2- 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? 3- Conduct your hypothesis test using =0 .01 as the level of significance. What is your conclusion?
