A study by the centers of disease control (CDC) found that 23.3% of smokers are adults and that roughly 70% of those who do smoke indicate that they want to quit (Associated Press, July 26, 2002). CDC reported that, of people who smoked at the point of their lives, 50%, have been able to kick the habit. Part study suggested that the success rose by education level. Assume that a sample of 100 college graduates who smoked at the point of their lives showed that 64 had been able to successfully stop smoking.

a. State the hypothesis that can be used to determine whether the population of the college graduates has a success rate higher that the overall population when it comes to breaking smoking habit.

b. Given the sample data, what is the proportion of college graduates who, having smoked at the point of their lives, were able to stop smoking?

c. What is the p-value? At a=0.01, what is your hypothesis testing conclusion?
