How do I do the following in Rmarkdown? Import the package nycflights13. Merge the flights and planes data into a new data frame.

Regress arr_delay on log(distance), seats, and origin using the merged data?

From there how can I determine which airport is the base cateory? What would be the meaning of the coef. of log(distance)?

How would I determine the coef. of seats being significantly different from -0.5 under the 5% significance level?
