15. According to research done by a University of California professor, the mean number of words spoken by a woman in a day is 20,000, with a standard deviation of 6000 words. The mean number of words spoken by a man in a day is 7,000, with a standard deviation of 2200 words. Assume that both distributions are normally distributed. Using this information, which is more unusual -- to randomly come across woman who speaks only 6,000 words a day or a man who speaks only 1,000 words a day? Explain briefly using z-scores and Standard Deviations from the mean
