A recent survey asked adults nationwide if they thought that the federal government should continue to fund Nasa’s efforts to send unstaffed missions to Mars. 56% said they should continue, 40% said they should not continue, and 4% had no opinion. A random sample of 200 college students resulted in these numbers: Should continue: 126 Should not continue: 65 No opinion: 9 Is there sufficient evidence at chi: 0.05 to conclude that the opinions of the college students differ from those of the report?
