I would appreciate help with the answers to all questions please. Thanks in advance.

Answer true or false. If false, explain briefly. a) Some of the residuals from a least squares linear model will be positive and some will be negative. b) Least squares means that some of the squares of the residuals are minimized c) We write y to denote the predicted values and y to denote the observed values. a) Choose the correct answer below. O A. The statement is false. Exactly half the residuals will be positive and half will be negative. O B. The statement is false. All the residuals will be positive. O C. The statement is true. O D. The statement is false. In a least square regression line all the residuals will be equal to 0. b) Choose the correct answer below. O A. The statement is true. O B. The statement is false. Least squares means the sum of the squared residuals is minimized O C. The statement is false. Least squares means only the negative residuals are minimized. O D. The statement is false. Least squares means only the largest residuals are minimized. c) Choose the correct answer below. O A. The statement is false. We use y to denote the predicted values and residuals to denote the observed values O B. The statement is false. We use bo to denote the predicted values and y to denote the observed values. O C. The statement is false. We use y to denote the predicted values and y to denote the observed values. O D. The statement is true. ? Click to select your
