Required information The depth of wetting of a soil is the depth to which water content will increase owing to external factors. An article discusses the relationship between depth of wetting beneath a structure and the age of the structure. The article presents meacu urements of denth of wettinc in meters, and the ages, in years, of 21 houses, as shown in the following table. Compute the least-squares line for predicting depth of wetting $(y)$ from age $(x)$. Round the answers to three decimal places. The least-squares line $y$ is The depth of wetting of a soil is the depth to which water content will increase owing to external factors. An article discusses the relationship between depth of wetting beneath a structure and the age of the structure. The article presents measurements of depth of wetting, in meters, and the ages, in years, of 21 houses, as shown in the following table. Identify a point with an unusually large $x$-value. Compute the least-squares line that results from deletion of this point. Round the answers to three decimal places. The equation of the least-squares line $y$ is $+x$.
