Newbie seeking help! MS summer IED position, 75 minutes, 10 statistics multiple choice questions + 2 coding questions. Statistics questions are all from BabyBus, probability, normality, Poisson, and matrix are all elementary level. The first coding question is also from BabyBus, about selecting all words with a frequency >= k from a given text. The second question is about function composition: five functions: add, square, splitter, max, min, write a function to combine them. Note that the five functions are already defined; you don't need to work on them, just write how to combine them.
