Question

20.37 Men of few words? Researchers claim that women speak signif 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 counts of the 20 men in the study were determined. Here are their daily word counts:24 28,408 10,084 15,931 21,688 37,786 10,575 12,880 11,071 17,799 13,182 8.918 6,495 8,153 7,015 4.429 10,054 3,998 12.639 10,974 5,255 (a) Examine the data. Is it reasonable to use the t procedures (assume these men are an SRS of all male students at this university)? (b) If your conclusion in part (a) is "'yes," do the data give convincing evidence that the mean number of words per day of men at this university differs from 7,000? Show Answer
