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 was found to have a mean of 16,367 words per day. Assuming the standard deviation for words spoken per day, whether male or female in the university is 3000 words, would it be valid at the .05 level of significance to conclude that the mean number of words per day of men at this university is less than that of women?

researchers claim that women speak more words per day than men. One estimate is that a woman uses about 15,500 words per day while a man uses about 11,500. To investigate such claims, one study used a special device to record the conversations of male and female university students over a 4-day period. Samples of 18 men were selected to provide evidence that the mean number of words per day of men at this university differs from 11,500. The sample...
