A political science study is planned to determine if offering voters a ride to the polls will increase the probability that the person will actually vote. One thousand voters are selected for the study. (The subjects don't know that they are in the study.) Five hundred people are randomly assigned to be offered a ride to the polls to vote. The other five hundred subjects are randomly assigned to not be offered a ride. The results are evaluated by checking voting records to determine whether the subjects actually voted on election day. The researchers find that subjects who are offered a ride were more likely to vote. Answer TRUE or FALSE to the two statements below. The people who are not offered a ride are the control group. TRUE FALSE This study will have a problem with response bias. TRUE FALSE This is a controlled experiment (designed experiment). TRUE FALSE What is the treatment in this study? A data set has the following ve number summary: minimum = 4 C11 = 12 median = 20 C13 = 24 maximum = 49 Is the maximum value (x = 49) an outlier? To get full credit you must show how your performed the test to determine if a number is an outlier
