Problem Set 07

Please Indicate

• Who you collaborated with. If no one, please indicate so:
• Approximately how much time did you spend on this problem set:
• What, if anything, gave you the most trouble:

Instructions:

• I highly recommend you go over the Problem Set 06 Discussion beforehand.
• Say you have your results in a data frame called results. Including kable(results) in your code will print the table in your HTML page in a nice and clean manner.

Question 1: Women and Children First

Research question: Did the “women-and-children” first policy hold? Hint: the answer is yes.

Argue your conclusion using the results from an outputed table. Do as much as you can computationally to minimize the number of hand calculations you may need to make (if any).

Your conclusion:

Question 2: America Runs on Starbucks?

Research question: Do Starbucks tend to locate in higher income neighbors, while Dunkin Donuts does not i.e. they tend to locate in lower income neighborhoods."

Recreate the plot in part a), but with any improvements you think are warranted in order to answer the question. Don’t worry about making the green/orange colors match.

Your conclusion:

Question 3: NYC Flights

Do parts c), d), and e)

Hint: For part e), you may need to lean on Google. Google is a Data Scientist’s best friend; effective Googling is a skill that needs developping. Example: Googling “DESIRED TASK dplyr” will return relevant results how to do a desired task, but specific to the dplyr package.

Question 4: Unisex Names… Revisited
