Question

1.)

Normal distributions represent _______ random variables.

• discrete
• continuous
• categorical

2.)

A random variable that can take on any number in a given interval is called a:

• continuous random variable
• interval random variable
• finite random variable
• infinite random variable
• discrete random variable

Answer 1

(1) Correct answer is continuous random variable because continuous random variable can take any value between two defined points where discrete random variable has very limited number of possible values. Number of values possible for continuous random variable is not limited, but are fixed between the two end points or defined points.

So, continuous random variable has a normal distribution shape/

(2) As already mentioned in part (1), continuous random variable is the variable which can take any value which is present between two specified values or interval values. Continuous random variable can have unlimited values possible between two data points where discrete random variable has limited possible values.

So, correct answer is continuous random variable.
