3. Based on your answers to the questions 1 & 2 on this quiz, explain whether you think the data is normally distributed or not.

4. Find the probability of guessing no more than 10 questions correctly on a 20-question multiple choice test. Each question has 4 choices. (Hint: binomial distribution).

Remember that your choice of technology (or whether you use technology at all) is up to you. Having said that, though, you must present me with a reasonable amount of work or at least explanations of what you did on the technology. Do not simply write answers.
