Decide whether a discrete or continuous random variable is the best model for each of the following variables: a. The time for a computer algorithm to assign an image to a category.
b. The number of bytes used to store a file in a computer.
c. The ozone concentration in micrograms per cubic meter.
d. The ejection fraction (volumetric fraction of blood pumped from a heart ventricle with each beat).
e. The fluid flow rate in liters per minute.

a) Continuous

b) Discrete

c) Continuous

d) Continuous

e) Continuous

Step-by-step explanation:

Discrete variable:

Countable amounts(0, 1, 2, 3,...)

Continuous variables:

Can be decimal values.

a. The time for a computer algorithm to assign an image to a category.

Time can have decimal values, so continuous

b. The number of bytes used to store a file in a computer.

The number of bytes is never decimal, so discrete

c. The ozone concentration in micrograms per cubic meter.

Can be decimal value, so continuous

d. The ejection fraction (volumetric fraction of blood pumped from a heart ventricle with each beat).

Can be decimal value, so continuous

e. The fluid flow rate in liters per minute.

Can be decimal value, so continuous

b is the correct answer
