Imagine a group of people on a remote island, where height and weight are perfectly correlated. Mean height is 67 inches with a standard deviation of 3; weight has a mean of 140 pounds with a standard deviation of 21. What would be the weight in pounds of a person who is 65 inches tall?

Precalculus question, image attached.
