Over the past few decades, public health officials have examined the link between weight and teen girls’ smoking. Researchers surveyed a group of 273 randomly selected teen girls between 12 and 15 years old living in Massachusetts . After four years, the girls were surveyed again. Sixty-three said that they smoked to stay thin. Is there good evidence that more than 30% of the teen girls smoke to stay thin?

After conducting the test, your decision and claim are

  1. Reject Ho: sufficient evidence to conclude that more than 30% of teen girls smoke to stay thin.
