1) in a comprehensive road test on all new car models, one variable measured is the time it takes a car to accelerate from 0 to 60 miles per hour. to model acceleration time, a regression analysis is conducted on a random sample of 129 new cars. given: r^2= 0.6960 approximately what percentage of the sample variation in acceleration time can be explained by the simple linear model? (points : 1) 8% -17% 0% 70%
2)the coefficient of correlation between x and y is r = 0.59. calculate the coefficient of determination r^2
