Researchers equipped random samples of 46 male and 58 female students from a large university with a small device that secretly records sound for a random 30 seconds during each 12.5-minute period over two days. Then they counted the number of words spoken by each subject during each recording period and, from this, estimated how many words per day each subject speaks. The female estimates had a mean of 16,177 words per day with a standard deviation of 7520 words per day. For the male estimates, the mean was 16,569 and the standard deviation was 9108. Do these data provide convincing evidence of a difference in the average number of words spoken in a day by male and female students at this university?

PROBLEM 1: Rewrite the problem and solve it. Show all procedures, computations and solutions. Researchers claim that women speak significantly more words per day than men in a certain university. One estimate is that a woman uses about 20,000 words per day. To investigate such claims, one study used a special device to record the conversations of male students over a four-day period. From these recordings, the daily word counts of the 20 men in the study were determined and...
