Question

Suppose a uniform random variable can be used to describe the outcome of an experiment with outcomes ranging from 40 to 90. What is the mean outcome of this experiment?

a) 65
b) 70
c) 75
d) 80

Answer 1

The mean outcome of a uniform random variable with outcomes ranging from 40 to 90 is 65.

Step-by-step explanation:

The uniform random variable describing the outcomes of an experiment ranging from 40 to 90 will have a mean outcome of (40 + 90) / 2, since in a uniform distribution the mean lies directly in the middle of the range of possible outcomes. Therefore, the mean outcome is (130) / 2 which equals 65.
