Inference for Linear Regression: - The idea: o The calculated intercept b0 is a statistic that estimates the population intercept B . The 0 calculated intercept b1 is a statistic that estimates the population intercept B1 . o We can thus perform inference for the two linear parameters (intercept & slope). We are particularly interested in the slope, which indicates whether there is really a linear relationship. o A slope of 0 means no true linear relationship
