The golf would weigh less than a gram, and the ball, if hit hard, would fly at least very far away due to the kinetic energy without any atmospheric drag.
The <u><em>correct answer</em></u> is:
He needs to select a more representative sample.
Explanation:
Choosing students from the basketball team for the sample he uses on a study of heart rates and exercise will be a biased sample.

In order to reduce the amount of bias, he should choose students from different groups throughout the school.
The answer is.....Type I or convex curves are characterized by high age-specific survival probability in early and middle life, followed by a rapid decline in survival in later life. They are typical of species that produce few offspring but care for them well, including humans and many other large mammals.
