. Question 11 Testing: Ho: p = 0.63 Ha:p > 0.63 Your sample consists of 134 subjects, with 81 successes. Calculate the test statistic 2 Rounded to 2 decimal places.. Question 12 - You wish to test the following claim a significance level of o = 0.01. Ho:p = 0.79 Ha:p 0.72 Calculate the test statistic, rounded to 3 decimal placesI Question \"I? v 0.1 O Ho:p = 0.1 Hi:p > 0.1 O Ho:p = 0.1 Hi:p # 0.1 O Ho: / = 0.1 Hi:p 0.1This test statistic leads to a decision to... 20 At 2 O reject the null O accept the null O fail to reject the null As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is is more than 0.3. O There is not sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is is more than 0.3. O The sample data support the claim that the proportion of stocks that went up is is more than 0.3. O There is not sufficient sample evidence to support the claim that the proportion of stocks that went up is is more than 0.3.. Question 20 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 52 stocks traded on the NYSE that day showed that 22 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 = 0.005. 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... O less than (or equal to) or O greater than od. This test statistic leads to a decision to... 412 p2 O reject the null O accept the null O fail to reject the null e. As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.79. O There is not sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.79. O The sample data support the claim that the population proportion is less than 0.79. O There is not sufficient sample evidence to support the claim that the population proportion is less than 0.79
