The popular candy Skittles comes in 5 colors. According to the Skittles website, the 5 colors are evenly distributed in the population of Skittle candies. So each color makes up 20% of the population. Suppose that we purchase a mid-size bag of Skittles. Assume this size bag always has 200 candies. In this particular bag, 50 are green. What is the probability that a randomly selected bag of this size has 50 or more green candies? (Note: the answer may...

Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor would...
