Homocedasticity in Compressive Strength Analysis by Juan Jose Rodriguez is a document available to read on EtoBox.
An experiment was conducted to determine how compressive strength (Y) of concrete is affected by the percentage of limestone powder (X1) and the proportion of water to cement (X2). A simple linear regression model was fitted using only X2. The coefficient of X2 interpreted as the change in compressive strength for every unit change in the proportion of water to cement. A confidence interval was determined for the coefficient and a hypothesis test was performed on the regression model. Studentized residuals
