The graphs are illustrations of biased and unbiased distributions.
The true statement is (d) R is biased, and W is unbiased
<h3>How to determine which of the graph is biased</h3>
From the graph, we have the following highlight
- The population parameter of graph R is at the right of the distribution
- The population parameter of graph W is at the center of the distribution
The above means that:
Graph R is biased, and graph W is unbiased
