Tutorial Starter Files

In today’s tutorial, you’re going to calculate some statistics for the Boston Marathon. To do this, you will open some of the files in the boston_marathon directory, loop through each line in the file, and perform some basic summary statistics.

Please write a program to calculate the following statistics. You can write each program as a separate file, or do all of the calculations in a single file. Up to you.

Please answer the following questions

1. How many people completed the Boston Marathon in 2015?

2. What was the average age of someone completing the Boston Marathon in 2015?
   • Hint: you may need to use try/except for any messy / unexpected data.
3. What was the average time of people who completed the Boston Marathon in 2015?
   • Hint: you will have to parse the total time into a number that can be summed. So, you may want to convert all of the times to seconds.

4. What was the average time for Kenyan runners who completed the Boston Marathon in 2015?

5. [If Time] What was the average time for female runners in their 30s in 2015?
