1). A survey asked San Diego residents the following question: “If you had been aware that before Arnold Schwarzenegger ran for Governor, he had fathered a child outside of his marriage, would you still have voted for him?” Out of the 150 males surveyed who had voted for Schwarzenegger 84 said they would still vote for him, and out of the 120 females 51 said they would. Does the data suggest that there is a difference between the proportion of...
