What is the Mean of the Men group? how about the Women group?

Noting that women seem more interested in emotions than men, a student in Experimental Psychology in UP Clark wondered if women recall emotional events better than men. She decides to gather some data on the matter. An experiment is conducted in which 5 randomly selected men, and 12 randomly selected women are shown 20 highly emotional photographs and then asked to recall them 1 week after the showing. The following recall data are obtained. Scores are percent correct. Distribution of participants between groups were not balanced since women are greater in number than men in the school.
