Every time you do a different sample, you will likely get a … WebSo we use a confidence interval to provide a range of values for the true slope. For our example, the average increase in Removal for every 1-unit increase in OD is between 0.462 and 0.595. The confidence interval for the slope provides an additional test for size of the slope coefficient. This might be easier to interpret and explain than a p ...
