Expert Solution
Step 1
Introduction:
A uniform distribution, also called a rectangular distribution, is a probability distribution that has constant probability.
This distribution is defined by two parameters, a and b:
- a is the minimum.
- b is the maximum.
The general formula for the probability density function (pdf) for the uniform distribution is:
f(x) = 1/ (B-A) for A≤ x ≤B.
Where “A” is the location parameter The location parameter tells you where the center of the graph is. “B” is the scale parameter. The scale parameter stretches the graph out on the horizontal axis.
