Good Thing I Didn't Waste Any Time Studying

Today we had a quiz in the graduate statistics class that I'm taking.

We were shown two sets of data, and we had to state which test we would use to determine whether they had the same mean. Then we had to interpret a 95% confidence interval. Next we had to identify a non-parametric test to compare the two data sets. Then we had to use the box plot to find the mean and the median. We had to describe the shape of the distribution (direction of skewness), one other question about skewness. We also had to calculate what type of prediction interval was shown.

Open book, open notes.
