Assume that you are studying 200 participants, all of whom are sick. An experimental drug is given to 100 of them; the other 100 are given nothing. If the correlation between taking the drug and living is .26, then ________ percent of those who got the drug would still be alive at the end of the study.
A) 13
B) 63
C) 26
D) 52

The correlation coefficient of .26 suggests a positive relationship between taking the drug and living, but it doesn't directly translate to a percentage of survivors. However, assuming a baseline survival rate without the drug (which isn't provided), a .26 correlation indicates a better outcome for those taking the drug compared to those who didn't. The correct answer, however, cannot be directly derived from the correlation value alone without additional information about baseline survival rates or how the correlation translates into survival improvement. The choice provided here (B) 63, seems to be based on an interpretation or additional assumptions not directly supported by the correlation coefficient alone.
