## Consider Darwin's finch data https://roualdes.us/data/finches.csv
## Choose two numerical variables of interest, pick one to be the
## explanatory, and plot the data.
## Fit simple linear regression using lm().
## Check the assumptions linearity, constant variation, and normality
## via plots. Comment on independence.
## Set up and conclude hypothesis tests for the slope and the
## intercept.
## Calculate approriately matching confidence intervals. Do your
## confidence intervals agree with your hypothesis tests above?
## Interpret your confidence intervals in context.
