A linear regression was run on a data set that includes the number of pieces in a building set (x) and the price of that set (y), resulting in the equation . Which of the following statements correctly interprets the value of 0.146 in the equation of the least-squares regression line? a. For a building set with 0 pieces, the model predicts the price to be $0.146. For each additional piece in the building set, the model predicts the price will increase $0.146.
b. For each additional piece in the building set, the model predicts the price will decrease $0.146.
c. For each additional dollar spent, the model predicts the number of pieces in the building set will increase by 0.146.
d. For each additional dollar spent, the model predicts the number of pieces in the building set will decrease by 0.146.
