College ClonICIt The percentage of female high school graduates who enrolled in college is given in the table below. Year College Enrollment Percentages for Females 1970 25.5 1980 30.3 1990 38.3 2000 45.6 2010 50.5 Let x represent time (in years) since 1970, and let y represent the corresponding percentage of female high school graduates who enrolled in college. Find the cubic regression model y = F(x) = ax' + bx2 + cx + d, where a is rounded to 6 decimal places, b is rounded to 4 decimal places, c is rounded to 3 decimal places, and d is rounded to 1 decimal place. Use this model to answer the questions below
