Let Q1 be the slope, Q2 the intercept of the linear regression line y = ax + b, and
Q3 the prediction ˆy0 = 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.
