Final answer:
The process involves using a calculator to create a scatter plot, find the least-squares regression line by minimizing the SSE, and interpreting the resulting regression parameters.
Step-by-step explanation:
The question relates to finding least-squares regression parameters that predict a player's value based on their age using root mean square error (RMSE) and optimization techniques such as the minimize function. Typically, this involves entering data into a calculator, creating a scatter plot, and applying the calculator's regression function to determine the least-squares regression line. This process minimizes the sum of squared errors (SSE), producing the equation ŷ = a + bx, where 'a' represents the y-intercept and 'b' represents the slope of the line. This equation is central to making predictions within the dataset.
Furthermore, interpreting the slope is crucial as it provides insights into the relationship between the independent variable (age) and the dependent variable (player value).
