3. Let Q1 be the slope and Q2 the intercept of the linear regression line y = ax + b, where the sequences x and y are as follows: x: 7, 83, 71, 66, 87, 31, 41, 62, 22, 42, 45, 77, y: 47, 98, 27, 88, 23, 90, 99, 100, 23, 23, 80, 38. 1

Let Q = ln(3 + |Q1|+ 2|Q2|). 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.
