Question

Question 5 (1 point) It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test the hypothesis that students who study one week before score less than students who study the night before. A hypothesis test for two independent samples is run based on your data and a p-value is calculated to be 2e-04. What is the appropriate conclusion? 1) The average score of students who study one week before a test is significantly less than the average score of students who wait to study until the night before a test. 2) The average score of students who study one week before a test is significantly different from the average score of students who wait to study until the night before a test. The average score of students who study one week before a test is significantly greater than the average score of students who wait to study until the night before a test. We did not find enough evidence to say the average score of students who 4) study one week before a test is less than the average score of students who wait to study until the night before a test. 5) The average score of students who study one week before a test is greater than or equal to the average score of students who wait to study until the night before a test. Question 6 (1 point) The federal government recently granted funds for a special program designed to reduce crime in high-crime areas. A study of the results of the program in high-crime areas of Miami, Florida, are being examined to test the effectiveness of the program. The difference in crimes reported is calculated as (crimes after - crimes before). You want to test whether the average number of crimes reported after are different from the average number of crimes reported before. What are the hypotheses for this test? 1) Ho: 40 = 0 HAMD 0 Ho: HD 0 HA: HD = 0 3) Ho: HD 20 HA: HD <0 4) Ho: HD > 0 HAUD 30 5) Ho: HD SO HALD > 0 O
