Over the past few decades, public health officials have examined the link between weight concerns and teen girls' smoking. Researchers surveyed a group of 273 randomly selected teen girls living in Massachusetts (between 12 and 15 years old). After four years the girls were surveyed again. Sixty-three said they smoked to stay thin. The null hypothesis states that there is good evidence that more than thirty percent of teenage girls smoke to stay thin. The alternative hypothesis is: p< 0.30 p≤ 0.30 p≥ 0.30 p> 0.30
