Question
Select all that applyWhich of the following is true regarding the graph depicting the normal probability density function f(x)?Multiple select question.Is often referred to as the normal curveIs not always symmetric around the meanIs often referred to as the bell curveIs symmetric around the mean
Solution
The correct answers are:
- Is often referred to as the normal curve
- Is often referred to as the bell curve
- Is symmetric around the mean
The normal probability density function, also known as the normal curve or bell curve, is always symmetric around the mean. This means that the left and right halves of the graph are mirror images of each other.
