D Use following info for next 10 questions, Scenario 1: A researcher wants to determine whether test performance is better after studying while listening to Led Zeppelin or after studying in complete silence. The researcher selects 11 students and has each of them take two different tests; one test following one hour of studying while listening to Kasmir by Led Zeppelin and the other test following one hour of studying in complete silence. The researcher calculates the mean test performance for each condition in order to compare them; the data are presented below. The researcher wants to Maximize the Power of the test. Led Zeppelin Silence 92 94 90 90 89 87 88 86 87 85 86 84 85 83 84 82 83 81 82 78 80 74 Means 86 84 Grand Mean - 85D Question 11 0.4 pts What are the Null and Alternative Hypotheses for the test of the means? Note: 1 = Led Zeppelin 2 = Silence (a) Ho: p1 s p2 H1: p1 > 12 (b) Ho: p1 2 2 H1: p1 2 H1: p1 s p2 O (e) Ho: p1 = p2 H1: p1 = H2 (f) None of thes are correct D Question 12 0.4 pts What is the correct alpha level for the test of the means?D Question 13 0.4 pts What is the correct observed test statistic value for this test is (Round to three decimal places)? D Question 14 0.4 pts What is the correct critical value for this test (Round to three decimal places)?D Question 17 0.4 pts If appropriate, calculate the 99% Confidence Interval. What is the value of the UPPER BOUND of this Confidence Interval? Note: Input Answer you calculate to 2 Decimal Places. Also Note: If it is NOT appropriate to calculate, input 999. D Question 18 0.4 pts If appropriate, calculate the 99% Confidence Interval. What is the value of the LOWER BOUND of this Confidence Interval? Note: Input Answer you calculate to 2 Decimal Places. Also Note: If it is NOT appropriate to calculate, input 999.D Question 19 0.4 pts If appropriate, calculate the Biased Effect Size. What is the value of the Biased Effect Size? Note: Input Answer to 2 Decimal Places. Also Note: If it is NOT appropriate to calculate, input 999. D Question 20 0.4 pts If appropriate, calculate the Uniased Effect Size. What is the value of the Uniased Effect Size? Note: Input Answer to 2 Decimal Places. Also Note: If it is NOT appropriate to calculate, input 999
