A Durbin-Watson test question

Could you please turn this into a self-contained reprex (short for minimal reproducible example)? That way we can be sure that we're looking at the same material, and no one has to go through the trouble of trying to type your code from a picture!

Right now the best way to install reprex is:

# install.packages("devtools")

If you've never heard of a reprex before, you might want to start by reading the tidyverse.org help page. The reprex dos and don'ts are also useful.

If you run into problems with access to your clipboard, you can specify an outfile for the reprex, and then copy and paste the contents into the forum.

reprex::reprex(input = "fruits_stringdist.R", outfile = "fruits_stringdist.md")
