Answer: a). The height of a randomly selected giraffe - a continuous random variable
b). The number of points scored during a basketball game - a discrete random variable
c). The eye color of people on commercial aircraft flights - a discrete random variable
d). The time it takes for a light bulb to burn out - a continuous random variable
e). The number of hits to a website in a day - a discrete random variable
f). The number of bald eagles in a country - a discrete random variable
a). The height of a randomly selected giraffe is B. It is a continuous random variable
Step-by-step explanation: A continuous random variable is a variable whose value is obtained by measuring; infinitely many values and the collection of values is not countable.
A discrete random variable is a variable whose value is obtained by counting; collection of values that is finite or countable.
Answer:
1. Continuous random variable
2. Discrete random variable
3. Not a random variable
4. Continuous random variable
5. Discrete random variable
6. Discrete random variable
The height of a randomly selected giraffe is a Continuous random variable.
Step-by-step explanation:
A random variable is a set of possible values that are obtained from a random experiment. They are usually assigned numerical values.
A discrete random variable is obtained by counting, whereas, a Continuous random variable is obtained through measurement. Therefore the following hold;
1. The height of a randomly selected giraffe is a continuous random variable because it is obtained through measurement.
2. The number of points scored during a basketball game is a discrete variable because it is obtained by counting.
3. The eye color of people on commercial air flights is a nominal variable. It is assigned a description, not a numerical value.
4. The time it takes for a light bulb to burn out is a continuous variable because it would have to be measured.
5. The number of hits to a website in a day is a discrete variable because it would have to be counted.
6. The number of bald eagles in a country would also be counted, thus making it a discrete variable.
