A Psychologist Obtained Recordings of Election-Night Acceptance Speeches of Seven

A psychologist obtained recordings of election-night acceptance speeches of seven newly elected representatives to the U.S.Congress and counted the number of minutes devoted to urban problems in these speeches.The four of these representatives from rural districts devoted 5,0,3,and 4 minutes to urban problems,and the three representatives from urban districts devoted 11,11,and 14 minutes to urban problems.Using the .05 significance level,did the amount of time devoted to urban problems in the acceptance speech differ according to the type of district the representative represented?
