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 70 stocks traded on the NYSE that day showed that 31 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.002α=0.002.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα greater than αα This test statistic leads to a decision to... reject the null accept the null…

The Watch Corporation of Switzerland claims that its watches on average will neither gain nor lose time during a week. A sample of 18 watches provided the following gains (+) or losses (-) in seconds per week +0.42 -e.35 0.12 e.59 0.21 0. 59 -0.71 e.74 0.62 -0.89 0.69 -0.67 0.30 -0.40 -0.36 0.54 0.41 0.74 Ho H=0 Is it reasonable to conclude that the mean gain or loss in time for the watches is 0? Use the 010 significance level. a. At a level of 0.10 significance, we reject Ho: µ = 0. (Negative answer should be indicated by a minus sign. Round the final answers to 3 decimal places.)
