The regression line y = 0.95x + 0.4 provides a linear model for the cost, y hundred dollars, associated with producing x components. What is the practical interpretation of the coefficient 0.95?

  1. (A)\0.135 is the cost of producing x$ components.
  2. (B)\135.00 is the cost of producing x$ components.
  3. (C)For every additional component of x that is produced the cost will increase by \95.00$.
  4. (D)For every additional component of x that is produced, the cost will increase by \0.95$.
