A sudent is analyzing data from an experiment using a linear model. when the student entered the data into his calculator and ran a least squares linear regression the calculator gave a correlation coefficient of 0.01. what can the student infer from this coefficient?
a. the slope of the linear model is 0.01
b. the yintercept of the linear model is 0.01
c. the xintercept of the linear model is 0.01
d. the linear model is not a good fit

a correlation coefficient of absolute value close to one is a good fit. A correlation coefficient close to zero is a poor fit. 0.01 is a poor fit.
