Question

1. determine whether each of the following describes a discrete random variable, continuous random variable, or neither. a. weight of a randomly selected monkey at a zoo b. number of car accidents on a randomly selected day c. the chosen political party of a randomly selected voter d. most recent race time of a randomly selected runner

Explanation:

a. Weight can take any value within a range (e.g., 5.2 kg, 5.23 kg) and is measurable, so it is continuous.
b. The number of car accidents is a countable whole number (0,1,2,...), so it is discrete.
c. A political party is a categorical label, not a numerical quantity, so it is neither a discrete nor continuous random variable.
d. Race time can take any value within a range (e.g., 10.25 seconds, 10.253 seconds) and is measurable, so it is continuous.

Answer:

a. Continuous random variable
b. Discrete random variable
c. Neither
d. Continuous random variable
