Question

Researchers equipped random samples of 56 males and 56 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 form 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. For the male estimates, the mean was 16, 569 and the standard deviation was 9108.
