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 71 stocks traded on the NYSE that day showed that 24 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 a = 0.01. 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) a greater than a This test statistic leads to a decision to... reject the null accept the null fail to…

How much more likely are alcoholics to say sober for a year after counseling if their best friend is not an alcoholic vs. if their best friend is an alcoholic? A researcher tracked 747 alcoholics whose best friends were not alcoholics and 517 alcoholics whose best friends were alcoholics. A year later 570 of those whose best friends were not alcoholics stayed sober for the year and 207 of those whose best friends were alcoholics stayed sober for the year. 1. Come up with the 99% confidence interval for the difference. Round your answers to four decimal places and present your answers as proportions rather than percents. ( __________ , ____________ )

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 55% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day. A sample of 79 stocks traded on the NYSE that day showed that 48 went up. You are conducting a study to see if the proportion of stocks that went up is significantly different from 55%.

UCLA conducted a survey of more than 263,000 college freshmen from 385 colleges in fall 2005. The results of students' expected majors by gender were reported in The Chronicle of Higher Education (2/2/2006). Suppose a survey of 5,000 graduating females and 5,000 graduating males was done as a follow-up last year to determine what their actual majors were. The results for males are shown in the table below. The second column in the table does not add to 100% because of rounding.Conduct a goodness-of-fit test to determine if the actual college majors of graduating males fit the distribution of their expected majors.

A financial analyst wants to understand the preference of the people investment strategy. A randomly selected people asked a question about the preference investment on their money either on "real estate" or "stock market". After collecting a data some statistical analysis is done to understand the main question of the analyst. Here is the financial analyst thought: A financial analyst thinks that there is an decreasing ratio on investing the money to "real estate " for last 5 years. In order to test the decrease in the preference of real estate a research is done and the following numbers are collected in 2010 and 2015. 20152010 Number of people asked 250 400 Number of people who prefer real estate 130 180 The analyst claims that there is a decreasing trend for every new year for investing the money to real estate. That means the ratio of people who invest their money to "real estate" in 2015 is less than that of in 2010. (H_{1}) : P 2010 >P 2015 ) Calculate test statistics.
