An article in Wood Science and Technology, "Creep in Chipboard, Part 3: Initial Assessment of the Influence of Moisture
An article in Wood Science and Technology, "Creep in Chipboard, Part 3: Initial Assessment of the Influence of Moisture Content and Level of Stressing on Rate of Creep and Time to Failure” (1981, Vol. 15, pp. 125-144) studied the deflection (mm) of particleboard from stress levels of relative humidity. Assume that the two variables are related according to the simple linear regression model. The data are shown below. . x = Stress level (%) 54 54 61 61 68 68 75 75 75 y = Deflection (mm) 16.477 18.695 14.306 15.125 13.507 11.642 11.171 12.535 11.226 (a) Test for significance of regression using a = 0.05.
