(b) What is the change in mean chlorine content when the degree of delignification increases from 7 to 8?




What is the change in mean chlorine content when the degree of delignification increases from 9 to 10?

A particular article proposed a quadratic regression model to describe the relationship between x = degree of delignification<br>during the processing of wood pulp for paper and y = total chlorine content. Suppose that the actual model is the following.<br>y = 230 + 75r –<br>4.x2 + e<br>
