Given: The Centers for Disease Control and Prevention Office on Smoking and Health (OSH) is the lead federal agency responsible for comprehensive tobacco prevention and control. OSH was established in 1965 to reduce the death and disease caused by tobacco use and exposure to secondhand smoke. One of the many responsibilities of the OSH is to collect data on tobacco use. The following data show the percentage of U.S. adults who were users of tobacco for a recent 11-year period (http://www.cdc.gov/tobacco/data_statistics/tables/trends/cig_smoking/index.htm).

And Given:
Slope is: bo = 0.2809
Intercept is: b1 = 21.9945
and MSE = 0.6654
Use your model to estimate the number of years that must pass after these data have been collected before OSH will achieve their goal of U.S. adults who were users of tobacco to 12% or less. Round your answer to the nearest whole number.
