Question description

Researchers claim that women speak significantly more words per day than men. One estimate is that a woman uses about 20,000 words per day while a man uses about 7,000. To investigate such claims, one study used a special device to record the conversations of male and female university students over a four- day period. From these recordings, the daily word count of the 20 men in the study was determined. Here are their daily word counts:

284061008415935 21695 37781 
10579 12876 11064 17789 13185 
8923 6486 8157 7022 4436 
10054 3998 12642 10964 5255 

A 90% confidence interval (10) for the mean number of words per day of men at this university is from ___ to ___ words.
