Question

determine whether the following value is a continuous random variable, discrete random variable, or not a random variable.
a. the time required to upload a file to the internet
b. the last book a person in city a read
c. the number of pigeons in a country
d. the time it takes for a light bulb to burn out
e. the amount of rain in city a during july
f. the height of a randomly selected person
a. is the time required to upload a file to the internet a discrete random variable, continuous random variable, or not a random variable?
a. it is a continuous random variable.
b. it is a discrete random variable.
c. it is not a random variable.
b. is the last book a person in city a read a discrete random variable, continuous random variable, or not a random variable?
a. it is a continuous random variable.
b. it is a discrete random variable.
c. it is not a random variable.

Explanation:

• a. Time is a continuous quantity. It can take any value within a range (e.g., \(0.5\) seconds, \(1.23\) seconds). So, the time required to upload a file is a continuous random variable.
• b. The last - book read is a non - numerical, categorical variable. Random variables must be numerical (either discrete or continuous). So, it is not a random variable.

Answer:

a. A. It is a continuous random variable.
b. C. It is not a random variable.
