DS 12.11.3 contains data from a set of automobile engines concerning the diameter of the bearing and the friction power loss that occurs in the bearing of the engine. Perform a linear regression analysis with power loss as the dependent variable and bearing diameter as the explanatory variable.
Can you conclude that there is a significant association between power loss and bearing diameter? What is the sample correlation coefficient? What can you predict for the power loss of a new engine with a bearing diameter of 25.0? Are there an\ data points with values c,/a larger than 3 in absolute value?
