(MAT-152-812K 20235U) Statistical Methods I 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). 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. A sample of 55 stocks traded on the NYSE that day showed that 15 went up. You are conducting a study to see if the proportion of stocks that went up is significantly less than 0.3. You use a significance level of a = 0.01. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic Unit 5 (8.2, 8.3, 7.2) Unit 7 Section 7.2: Hypothesis Testing What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value= The p-value is... Oless than (or equal to) a Ogreater than a This test statistic leads to a decision to... reject the null accept the null fail to reject the null
