Reconsider the previous exercises about the study of whether there is an association between number of Facebook friends and a person€™s sex. The following is output from carrying out the randomization test using the Multiple Means applet.

Recall that the summary statistics about the data are as follows:

a. On the above histogram, shade the region that depicts the p-value.
b. Use the information available to find and report the standardized statistic in this context.

Data from previous exercise

The p-value for the randomization-based test of whether the average number of Facebook friends men have is different from that of women turns out to be 0.052

In a survey of introductory statistics students, an instructor asked her students to report how many Facebook friends they had. Suppose that the intent is to study whether there is an association between number of Facebook friends and a person€™s sex.
