Humberto Berry · Answer 1

A. Continuous, B. Discrete, C. Continuous, D. Continuous, E. Continuous.

Step-by-step explanation:

A. Area is a continuous unit. Then, the floor area of a kitchen is a continuous random variable.

B. Quantity is a discrete unit. Then, the number of bacteria in a particular cubic centimeter of drinking water is a discrete random variable.

C. The money amount is a continuous unit. Then, the dollar amount of the change in my pocket is a continuous random variable.

D. The pressure is a continuous unit. Then, the barometric pressure at a given location is a continuous random variable.

E. Time is a continuous unit. Then, the difference in reaction time to the same stimulus before and after training is a continuous random variable.
