Question
To study the effectiveness of a certain adult reading program, researchers will select a random sample of adults who are eligible for the program. The selected adults will be given a pretest before beginning the program and a post-test after completing the program. The difference in the number of correct answers on the pretest and the number of correct answers on the post-test will be recorded for each adult in the sample.Which of the following is the most appropriate inference procedure for the researchers to use to analyze the results? *
4 points
A) A one-sample z-interval for a population proportion
B) A one-sample t-interval for a sample mean difference
C) A two-sample t-interval for a difference between means
D) A matched-pairs t-interval for a sample mean difference
E) A matched-pairs t-interval for a population mean difference

Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 89 people were asked the voter registration question face to face. Of those sampled, seventy-six respondents gave accurate answers (as verified by city records). Another random sample of 90 people were asked the same question during a telephone interview. Of those sampled, eighty-three respondents gave accurate answers. Assume the samples are representative of the general population.

- College Board, the company that runs AP testing, wants to expand access to AP courses. Some schools require that students takethe AP exam at the end of the course while others leave the AP exam as optional. A random sample of 200 students from schoolswhere AP exams are required had 84 students currently enrolled in at least one AP course. Another random sample of 190students from schools where the AP exam is optional had 98 students currently enrolled in at least one AP course.(a) College Board want to test the claim that requiring the AP exam lowers the proportion of students who enroll in at least oneAP course. Carry out a test of this claim at the 5% level of significance. (b) Based on your decision in part (a), what error may have been made, a Type I or Type II error? Give a consequence of thaterror.

- The school district sets up two locations to help students with technical difficulties over the summer. They believe the technicians they have assigned to location 2 are being lazy and not helping students as much as they should be so they take a random sample of 15 students from each of the two locations and ask if their technical issue had been resolved (over 200 students had asked for assistance at each location). Twelve of the 15 students from location 1 reported their technical issue had been resolved and 8 of the 15 students from location 2 reported their technical issue had been resolved. Is this convincing evidence that the technicians from location 2 are being lazy and not helping students as much as those from location 1?arrow_forwardTo study the effectiveness of a certain adult reading program, researchers will select a random sample of adults who are eligible for the program.
