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: 80, 33, 24, 64, 18, 76, 43, 99, 12, 42, 12, 0,

y: 10, 47, 89, 22, 45, 35, 93, 100, 57, 27, 7, 95. 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
