According to a study, the probability that a smoker will quit smoking increases with the smoker's educational level. The probability (expressed as a percent) that a smoker with x years of education will quit is approximated by the equation f(x) = 0.831x² 18.1x + 137.3 (for 10 ≤ x ≤ 16).t (a) Find f(12). (Round your answer to three decimal places.) f(12) = 39.764 ✓ Interpret this number. [Hint: x = 12 corresponds to a high school graduate.] A smoker who is a high school graduate has a X % chance of quitting. Find f'(12). (Round your answer to three decimal places.) f'(12) = 1.844 ✓ Interpret this number. [Hint: x = 12 corresponds to a high school graduate.] When a smoker has a high school diploma, the chance of quitting is increasing ✓ (b) Find f(16). (Round your answer to three decimal places.) f(16) = Interpret this number. [Hint: x = 16 corresponds to a college graduate.] A smoker who is a college graduate has a Find f'(16). (Round your answer to three decimal places.) f'(16) = %…
