The following data represent the time between eruptions and the length of eruption for 9 randomly selected geyser eruptions. The coefficient of determination is 90.6 %.

Time, x Length, y Time, x Length, y
12.05 1.80 11.46 1.64
11.73 1.80 11.58 1.67
12.06 1.81 12.19 1.90
12.21 1.88 11.52 1.76

Choose the best interpretation below.

(A) 90.6% of the variation in time between eruptions is explained by the least-squares regression equation.
(B) 90.6% of the variation in time between eruptions is not explained by the least-squares regression equation.
(C) 90.6% of the variation in length of eruption is explained by the least-squares regression equation.
(D) 90.6% of the variation in length of eruption is not explained by the least-squares regression equation.
