A psychologist was interested in whether there was a gender difference in the use of email. She hypothesized that because women are generally better communicators than men, they would spend longer using email than their male counterparts. To test this hypothesis, the researcher sat by the email computers in her research methods laboratory and when someone started using email, she noted whether they were male or female and then timed how long they spent using email (in minutes). How should she analyse the differences in males and females? (Use the output below to help you decide.)
A) Paired t-test
B) Mann-Whitney test
C) Wilcoxon signed-rank test
D) Independent t-test
