random phenomenon
-Solution
an observable or virtual happening that can have multiple possible
outcomes, none of which happen with certainty
applied probability theory
-Solution
a mathematical model for describing and studying random
phenomenon
statistical inference
-Solution
involves making a statement about an entire population based on
observations in a sample.
probability theory
-Solution
provides a basic for measuring the reliability or risk associated
with statistical inferences
