Once again, we can use R to determine and display the data points and best-fit line with one of the built-in data sets. To do this, that data set needs to have the opportunity to utilize paired data. Below, we use the ’cars’ data set since that set has speed paired with a corresponding stopping distance from some experiment. See if you can use one of the other data sets to create a best-fit line and determine if the correlation coefficient is sufficiently ’good’ or not.
