Question

determine whether the value is a discrete random variable, continuous random variable, or not a random variable.
a. the weight of a t - bone steak
b. the number of people in a restaurant that has a capacity of 150
c. the political party affiliation of adults in the united states
d. the number of hits to a website in a day
e. the number of people with blood type a in a random sample of 17 people
f. the amount of snowfall in december in city a
a. is the weight of a t - bone steak a discrete random variable, a continuous random variable, or not a random variable?
a. it is a discrete random variable.
b. it is a continuous random variable.
c. it is not a random variable.
b. is the number of people in a restaurant that has a capacity of 150 a discrete random variable, a continuous random variable, or not a random variable?
a. it is a discrete random variable.
b. it is a continuous random variable.
c. it is not a random variable.

Explanation:

• a. The weight of a T - bone steak can take on any value within a range and is measured on a continuous scale, so it's a continuous random variable.
• b. The number of people in a restaurant is a countable quantity, so it's a discrete random variable.
• c. Political party affiliation is a categorical variable, not a numerical random variable of the types asked about.
• d. The number of hits to a website is a countable value, so it's a discrete random variable.
• e. The number of people with blood type A in a sample is a countable value, so it's a discrete random variable.
• f. The amount of snowfall can take on any value within a range and is measured on a continuous scale, so it's a continuous random variable.

Answer:

a. B. It is a continuous random variable
b. A. It is a discrete random variable
c. It is not a random variable of the types asked
d. A. It is a discrete random variable
e. A. It is a discrete random variable
f. B. It is a continuous random variable
