Darley and Latane (1968) asked subjects to participate in a discussion carried out over an intercom. Aside from the experimenter to whom they were speaking, subjects thought that there were zero, one or four other people (bystanders) also listening over the intercoms. Partway through the discussion, the experimenter feigned serious illness and asked for help. Darley and Latane noted how often the subject sought help (in the first five minutes) for the experimenter as a function of the number of bystanders. The data are as follows: Sought help Didn't seek help 19 2 Zero Number of Bystanders 16 8 One 8 22 Four 1.) Perform the necessary analysis to determine if there is a difference in the likelihood of seeking help depending upon the number of "bystanders". Is it statistically significant? (worth 8 points) 2.) Calculate and report the effect size for the above result. (worth 2 points) 3.) If a population of personality scores is normally distributed and has a mean of 200 and a standard deviation of 15, what is the probability that someone will score higher than 235? (6 points)
