Answer:
b. False
Explanation:
The number of costumers that visit your store is a DISCRETE variable because is the set of countable costumers. We count a whole person not parts of a person.
For a continuous variable we are allowed to take any value in an interval. In our case we can not say we had 3.4 costumers. We can say the costumer bought 3.4 gallons of gas for their car.
number or costumers →discrete variable
number of gallons of gas →continuous variable
b. False
