Solve the problem.The following table shows the median number of hours of leisure time that Americans had each week in various years.
(i) Use a graphing calculator to fit a quadratic sequence regression function an = an2 + bn + c to the data, where n is the number of years after 1973. (ii) Estimate the median number of leisure hours per week in 2000 and 2010. Round to the nearest hour.
A. (i) an = -0.04x2 + 1.21x + 26.03; (ii) 30 hours; 16 hours B. (i) an = 0.04n2 - 1.21n + 26.03; (ii) 23 hours; 36 hours C. (i) an = -0.021n2 + 1.44n + 28.07; (ii) 52 hours; 53 hours D. (i) an = 0.021x2 - 1.44x + 28.07; (ii) 4 hours; 4 hours
