This document contains data with x and y values for 15 data points. It performs a linear regression analysis to find the line of best fit and calculates the correlation coefficient (r) and coefficient of determination (r^2). It finds the line of best fit to be y = 0.128x + 435.61 with r^2 = 0.727, indicating a strong positive correlation between x and y.
