Question

determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. the number of bald eagles in a country b. the number of fish caught during a fishing tournament c. the political party affiliation of adults in the united states d. the amount of snowfall in december in city a e. the number of hits to a website in a day f. the number of statistics students now reading a book a. is the number of bald eagles in a country a discrete random variable, a continuous random variable, or not a random variable? a. it is a continuous random variable. b. it is a discrete random variable. c. it is not a random variable.

Explanation:

A discrete random variable has a countable number of possible values. The number of bald eagles in a country can be counted (e.g., 100, 200 etc.), so it is a discrete random variable. The number of fish caught, number of hits to a website, and number of statistics students reading a book are also countable and thus discrete random variables. The amount of snowfall is a continuous random variable as it can take on any value within a range (e.g., 5.5 inches, 10.25 inches etc.). Political - party affiliation is not a random variable in the traditional numerical sense as it is a categorical variable.

Answer:

a. B. It is a discrete random variable.
b. B. It is a discrete random variable.
c. C. It is not a random variable.
d. A. It is a continuous random variable.
e. B. It is a discrete random variable.
f. B. It is a discrete random variable.
