The file called "Assignment 2" is the homework problems which are about linear regression. The data for the lab section in the homework is the .rda file, and a reference paper named Challenger Paper might help you with the lab problem. Please use R application to solve the lab problems.
You can write the solution by either in LaTex or on the paper and upload a scanned copy.
I set the deadline by Thursday but if you could, please finish the work as soon as possible.
I really appreciate your help. Thank you so much!
