Do women talk more? Conventional wisdom suggests that women are more talkative than men. One study designed to examine this stereotype collected data on the speech of 10 men and 10 women in the United States. The variable recorded is the number of words per day. Here are the data:
(a) Summarize the data for the two groups using numerical and graphical methods. Describe the two distributions.
(b) Compare the words per day spoken by the men with the words per day spoken by the women using the Wilcoxon rank sum test. Summarize your results and conclusion in a short paragraph.
