(A) the number of heads resulting from flipping a coin 30 times (B) the number of deaths from plane crashes in a year (C) the proportion of the American pop- ulation that believes in ghosts (D) the number of films produced in Canada in a year (E) the number of people arrested for auto theft in a year
Jaylen surveys 85 students at random to determine the proportion of students who have attended Mt. San Jacinto College for more than two years. Suppose that, in reality, 32% of students have attended for more than two years. How are the collection of all sample proportions of samples of size 85 distributed? N(__,__) 2. What is the probability that fewer than 21% of students in Jaylen's sample have been enrolled for more than two years? List the z-scores needed to calculate the result. If there is more than one z-score, separate the values with a comma. There is a ___ chance that fewer than 21% of students in Jaylen's sample have been enrolled for more than two years.

In one of the archaeological excavation sites, the artifact density (number of prehistoric artifacts per 10 liters of sediment) was . Suppose you are going to dig up and examine liters of sediment at this site. Let 0, 1, 2, 3,… be a random variable that represents the number of prehistoric artifacts found in your liters of sediment. Compute the probability that in your liters of sediment you will find prehistoric . Round your answer to the nearest ten thousandth.
