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 NSW (between 12 and 15 years old). After four years the girls were surveyed again. Sixty-three said they smoked to stay thin. Is there good evidence than more than thirty percent of the teen girls smoke to stay thin? After conducting the test, your decision and conclusion are: Select one: O a. Reject the null hypothesis: There is sufficient evidence to conclude that more than 30% of teen girls smoke to stay thin. O b. Do not reject the null hypothesis: There is not sufficient evidence to conclude that less than 30% of teen girls smoke to stay thin. O c. Do not reject the null hypothesis: There is not sufficient evidence to conclude that more than 30% of teen girls smoke to stay thin. O d. Reject the null hypothesis: There is sufficient evidence to conclude that less than 30% of teen girls to stay thin.
