A student collected data on the number of large pizzas consumed, y, while students were watching a professional football game on TV. The data from five games are given in Table 2. 6 3 4 Number of students, x Number of large pizzas, y 2 1 5 6 10 3 5 Table 3: Data for problem 6 (a) (2 points) The least squares estimate of y-intercept coefficient is i. 2.1 ii. -3.4 iii. -0.9 iv. 2.0 (b) (2 points) The least squares estimate of slope coefficient is i. 2.1 ii. -3.4 iii. -0.9 iv. 2.0 (c) (2 points) The estimated regression line is i. Ÿ= -0.9 – 2x ii. Û = 2 – 0.9x iii. Ÿ= 2.1 – 3.42 iv. Î= -3.4 + 2.1.2 (d) (2 points) If the number of students watching the game is increased by one, the average number of pizzas consumed will increase by 3.4. i. True ii. False
