3.22 Exit poll. Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walker. They found that 53% of the respondents voted in favor of Scott Walker. Addition- ally, they estimated that of those who did vote in favor for Scott Walker, 37% had a college degree, while 44% of those who voted against Scott Walker had a college degree. Suppose we randomly sampled a person who participated in the exit poll and found that he had a college degree. What is the probability that he voted in favor of Scott Walker?43

1. Explain the MVA table based image.
Problem 1 91 percent of 16-24 year olds use social networks like instagram, snapchat, twitter and Face- book. A study done by the UK's Royal Society for Public Health (RSPH) and the Young Health Movement surveyed 1,500 randomly selected people ages 14 to 24 about how social networking sites and apps impact their mental health, including anxiety, depression, self- identity, and body image. The goal of the study was to rate social media platforms based on their overall impact on users. Their results indicated that Instagram had the most negative impact followed by Snapchat, Facebook, Twitter and, the most positive, Youtube. 1. What is the research question of this study? 2. Is this an observational study or an experiment? If this is an experiment state the explanatory variable and the response variable. 3. What is the sample used in the study? 4. What is the corresponding population? 5. Do you think the results of the study might be applicable (generalizable) to the whole population? Why…
