Problem
A stonemason wants to look at the relationship between the density of stones she cuts and the depth to which her abrasive water jet cuts them. The data show a linear pattern with the summary statistics shown below:
mean | standard deviation | |
---|---|---|
Find the equation of the least-squares regression line for predicting the cutting depth from the density of the stone.
