Question: Conspiracy Theory In a recent survey, Americans were asked about 20 popular conspiracy theories. Thirty-seven percent of voters believe global warming is a hoax, 21% are certain a UFO crashed in Roswell, New Mexico, and 7% believe the moon landings were faked. (You might consider investigating the theory about lizard people who control our society.) The survey results were often very different according to political affiliation. A random sample of Democrats and Republicans were asked if they believe pharmaceutical companies invent new diseases to make money. The resulting data are given in the following table.
Is there any evidence to suggest that the proportion of voters who believe pharmaceutical companies invent diseases to make money is different for Democrats and Republicans? Use a = 0.01.
