The drying time of varnish depends on the amount of certain chemical that s added.
a. Determine a best (least-squares) ft parabola of the form:
T(m) = x1 + x2m + x3m^2 to the data provided n the table below
b) Also, estimate the drying time of the varnish when 3.5 grams of the chemical are added.
Mass (m) of Additive (Grams) Drying Time (T) (Hours)
