If you randomly selected three voters and asked if they favor an increase in property taxes for road construction in the county. What is the sample space. (a) 6 (b)7 (c)8 (d 9 11. The scienilfic method has beon defined as a systematic, ompirical, controlled and critical examination of hypothetical propositions about the association among natural phenomena (a) True (b) False 12 Quasi-experimental rosearch shares smilartis with the traditional experimental design or randomized controlled trial, but they specifically lack the element of random assignment to treatment or control (a) True (b) Faise 13. Students take a 100- point true/talse exam, Assume the test is scored such that a student receives one point for a correct answer and loses a point for an incorrect answer. For example, assume a student knew 90 of the answers and guessed correctly on 7 of the remaining 10 (and therefore incorrectly on 3). Their true score would be 90 since that is the number of answers they knew. Their actual test score would be 90+4. What's their error score? (a) 7 (b) 3 (c)4 (d) o 14. Below experimental Designs is a within-subjects design efTaring Fren Group theraphy Ptychethenapy (a) True (b) False 15. The disadvantages of a Within-Subjects Design is a'carryover effect and practice effects'. (a) True (b) False 16. A false negative in screening tests (miss) (e.g, Steroid testing of athletes) represents the event that a. the test is negative for a given condition, given that the person does not have the condition b. the test is positive for a given condition, given that the person does not have the condition c. the test is negative for a given condition, given that the person has the condition d. the test is positive for a given condition, given that the person has the condition 17. A random sample of 25 blood donors was given a blood test to determine their blood type. The pie chart below shows the distribution of the blood types of these 25 donors. (Note: A, B, O and AB are the blood types)Explanation / Answer
(10) The set of all possible outcomes of an experiment is call sample space .If you randomly selected three voters and asked if they favour an increase in property taxes for road construction in the country what is the sample space
Ans:sample space{(0,1)(0,2)(0,3)(1,2)(1,3)(2,3)}
the sample space is 6
(11) the scientific method has been defined as asystematic emprical,controlled and critical examination of the hypothetical proportions about the association amaong natural phenomena
Ans:TRUE
(12) quasi experimental research shares simillarities with the traditional experimetal design or randomized controlled trail but they specifically lack the element to random assignment to treatment or control
