(a) Fit a linear regression model.
(b) Does it appear that the proportion of impurities passing through helium
increases as the temperature approaches –273 degrees centigrade?
(c) Does temperature has a significant influence on proportion of impurities
passing through the solid helium? Use Họ: B1 = 0 versus H1: B1 + 0.
(d) Based on the information above, does the linear model seem appropriate?
Support your answer with appropriate additional information.
