A certain agency has a goal of reducing the death and disease caused by tobacco use and exposure to second-hand smoke. One of the many responsibilities of the agency is to collect data on tobacco use. Suppose the following data show the percentage of adults in the United States who were users of tobacco during an 11-year period: Year Percentage of Adults Who Smoke 1 22.6 2 22.3 3 21.4 4 20.7 5 20.7 9 20.6 7 19.6 8 20.4 9 20.4 10 19.1 11 18.7 (b) Use simple linear regression to find the parameters for the line that minimizes MSE for this time series. (Round your answers to three decimal places.) b = (c) One of the agency's goals is to cut the percentage of adults in the United States who were users of tobacco to 12% or less by year 20. Find the forecast of the percent of adults who smoke for year 20. (Round your answer to one decimal place.) 20 96 Does your regression model from part (b) suggest that the agency is on target to meet this goal? O Yes O No If not, use your model from part (b) to estimate the year in which the agency will achieve this goal. (Enter 20 if the goal will be met by year 20.)
