- Suppose 40 participants complete an experiment whero ads are presented subliminally during a task) ads are at very fast rates during movie ads)Participants are then given a recognition test of images of the ads, where two images are presented and participants must choose which of the two was presented earlierBoth men and women (20 of each gender) participate in the study and the researcher predicts that the recognition accuracy will offer across gender. The difference between the sample means in this study was 5%. The for the men was 350 and the the women was 250. What is your t value? A) 3 B) 4.69 C) 3.54 D) 4Suppose population 1 consists of all students who picked up all the tests they completed prior to taking the final exam. Suppose population 2 consists of all students who had one or more tests that they completed that were not picked up prior to taking the final exam. Based on years of grading final exams and observing grades, STAT 210 instructors conjecture that the mean final exam grade for all students who picked up all their tests is greater than the mean final exam grade for all students who had one or more tests that were not picked up. A simple random sample of 56 students who picked up all tests they completed was selected, and the mean score on final exam for this sample of students was 83 with a standard deviation of 10.4. An independent simple random sample of 51 students who had one or more tests that were not picked up was selected, and the mean score on the final exam for this sample of students was 67 with a standard deviation of 24.2. Both distributions are skewed…-Work-Microsoft Edge ps://testnavclient.psonsvc.net/#/question/9d8da897-7504-4896-b4bb-a2932d472835/a72f044b-928a-49ae-80b2-f0d432db5ee1 Bookmark ▸ A X ← Review METRY FINAL EXAM 2021-22 / 2 of 21 Circle O has diameter AB and chord AC.
