Question

< Question 15 of 18 > 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. The table contains their daily word counts. 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 To access the complete data set, click the link for your preferred software format: Excel Minitab JMP SPSS TI R Mac-TXT PC-TXT CSV Crunchit!
