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 = 24.56, where the sequences x and y are as follows: x: 23, 18, 52, 7, 68, 95, 84, 36, 56, 58, 95, 83, y: 89, 11, 66, 29, 87, 66, 75, 91, 5, 19, 44, 70. 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.
