I am currently a second year science student double majoring in biochemistry and applied statistics. The stats course im doing this semester (Statistical Theory) is focused on joint probability distributions, moments of univariate distributions, moment generating function, distribution of sample statistics and parameter estimation. We have no recommended textbook for this course (instead my college offers their own notes with tutorial exercises at the end). I wrote my first test for this course and it turns out that the tutorial exercises are extremely easy (and few) in comparison. Can anyone recommend a textbook with practice questions so i can become more confident with anything they might throw my way??
