determine whether the following value is a continuous random variable, discrete random variable, or not a random variable.\na. the exact time it takes to evaluate 67 + 29\nb. the hair color of adults in the united states\nc. the number of people in a restaurant that has a capacity of 250\nd. the number of free - throw attempts before the first shot is missed\ne. the time it takes for a light bulb to burn out\nf. the number of textbook authors now eating a meal\na. is the exact time it takes to evaluate 67 + 29 a discrete random variable, continuous random variable, or not a random variable?\na. it is a discrete random variable.\nb. it is a continuous random variable.\nc. it is not a random variable.
Answer
Brief Explanations:
- a. The time to evaluate 67 + 29 can take on any value within an interval, so it's a continuous random variable.
- b. Hair - color is a categorical variable, not a random variable in the numerical sense.
- c. The number of people in a restaurant is a countable quantity, so it's a discrete random variable.
- d. The number of free - throw attempts is a countable quantity, so it's a discrete random variable.
- e. The time for a light - bulb to burn out can take on any value within an interval, so it's a continuous random variable.
- f. The number of textbook authors eating a meal is a countable quantity, so it's a discrete random variable.
Answer:
a. B. It is a continuous random variable b. Not a random variable c. Discrete random variable d. Discrete random variable e. Continuous random variable f. Discrete random variable
