Question

Given the information, find the equation for the least squares line as well as the correlation coefficient.

n = 8,

x = 40,

y = 48,

xy = 240,

x2 = 210,

y2 = 288

What does y =

What does r =

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
