Question

Researchers did a study to compare how much men and women talk because it is commonly

thought that women talk more than men. The study collected data from a simple random

sample of women and a simple random sample of men. For each individual in these samples

the researchers gave the estimated number of words spoken by her/him in a day. The data is

in an Excel file on Canvas.

(a) Do the data provide good evidence that women talk more than men, on

average? State the null and alternative hypotheses relative to this question.

(b) Find the t test statistic.

(c) What is the P -value for your t?

(d) Does the data support the researchers idea?
