Question

Highway patrol officers measure the speed of automobiles on a highway using radar equipment. The random variable in this experiment is speed, measured in miles per hour. This random variable is a _____. a. discrete random variable b. continuous random variable c. complex random variable d. None of the answers is correct.

Answer 1

Answer:

b. continuous random variable

Step-by-step explanation:

Speed is a common continuous variable and the value is always random.

It is continuous because there is always another speed value between two speed values. For example, a car travelling at the rate of 50 mils per hour will either increase or decrease its speed at a continuous rate. No speed can drop suddenly form 50mph to 20mph.

It is random because although there might be speed limit, the speed recorded by the Highway patrol officer willl always be random in value.
