Hello, I just received an email asking me to complete a 3 hour data analysis and coding quiz sometime in the next few days as part of the University of Chicago Pre-Doc positions interview process. Has anybody taken a similar quiz that may be able to tell me what I can expect? This is my first time doing this for an academic interview, however, I've taken IBM's coding quiz for a software development position in the past. I plan on brushing up with a couple questions on HackerRank, but I'm not sure if this is going to help seeing that this is a data quiz and I haven't heard the language requirements. Any advice would be great, I haven't had an acceptance come in yet so I'm really hoping to continue this interview process. Thank you!

For question #17 in the GRE Official Guide, under the Data Analysis exercises: For 2001, private school expenditures were approximately what percent of total expenditures? A chart is given that displays $30 billion was private expenditures and $160 billion was total expenditures. So I took $30 is x% of $160 or 30/160 = 18.75%. The answer should be 19%. There's no instructions to round up so I can't figure out what I'm doing wrong?
