A forester would like to know how big a maple tree might be at age 50 years.She gathers data from some trees that have been cut down,and plots the diameters (in inches)of the trees against their ages (in years).First she makes a linear model.The scatterplot and residuals plot are shown.Do you think the linear model is appropriate? Explain. 
Maple Tree
A type of deciduous tree known for its distinct leaf shape and often valued for its sap, which can be made into syrup.
Linear Model
A numerical model that illustrates the proportional effect of one or more factors to another.
Scatterplot
A scatterplot is a type of graph used in statistics to display values for two variables for a set of data, showing how much one variable is affected by another.
- Review the relevance of linear regression models by checking residual patterns and R-squared values.
- Familiarize oneself with the concept of re-expression in the realm of linear regression and its applications.
