A study was performed on a type of bearing to find the relationship of amount of wear y to x₁ = oil viscosity and
x2 = load. The accompanying data were obtained. Complete parts (a) and (b) below.
Click the icon to view the bearing data.
(a) The model y₁ = ẞo + ẞ1×1; + B2×2; + B12x1,x2i+, for i = 1, 2, ..., 6 may be considered to describe the data. The
X1X2 is an "interaction" term. Fit this model and estimate the parameters.
ŷ = + (1) ×₁ + (x2+ (×1×2
(Round the constant to the nearest integer as needed. Round the x₁x2-coefficient to five decimal places as needed.
Round all other coefficients to three decimal places as needed.)
