17. A campus program evenly enrolls undergraduate and graduate students. If a random sample of 4 students is selected from the program to be interviewed about the introduction of a new fast food outlet on the ground floor of the campus building, what distribution should be used to calculate the probability that 3 out of 4 students selected are undergraduate students?
a. Binomial distribution
b. Poisson distribution
18. Based on the information in question 17, please find the probability that 3 out of 4 students selected are undergraduate students. (Please show your calculation process)

A psychology major recently conducted a survey with a random sample of 38 undergraduate students. She found that 18% of those surveyed stated that their preferred superpower would be teleportation. An article in a popular magazine stated that 33% of college students would choose teleportation as their preferred superpower. At Alpha = 0.10, test the claim that the proportion of students preferring teleportation is less than 33%?

Let's say you want to poll a random sample of 150 students on campus to see if they prefer to take online classes. Of course, if you took an actual poll you would only get one number (your sample proportion, p-hat). But, imagine all the possible samples of 150 students that you could draw and the imagined histogram of all the sample proportions from those samples. 1. What shape would the histogram of all the possible sample proportions (p-hat's) have?...
