4. Let Q1 be the slope, Q2 the intercept of the linear regression line y = ax + b, and Q3 the prediction y0 = ax0 + b for x0 = 20.77, where the sequences x and y are as follows: x: 94, 83, 15, 85, 22, 82, 10, 19, 21, 57, 57, 92, y: 52, 45, 7, 84, 34, 49, 82, 42, 95, 17, 84, 54. Let Q = ln(3 + |Q1|+ 2|Q2|+ 3|Q3|). Then T = 5 sin2(100Q) satisfies: (A) 0 T < 1. (B) 1 T < 2. (C) 2 T < 3. (D) 3 T < 4. (E) 4 T 5.
