An experimental study because it will give the most accurate results.
Step-by-step explanation:
The observational study could also be somewhat useful, but the most accurate results will come from an experimental study. You will test the difference in DNA, blood pressure, and such.

A linear equation is an equation that represents a line. A linear equation has a variable raised to the 1st power.
For example, Y = 2x, Y = x + 1, Y = 8x - 3 are examples of linear equations.
However, something like and seem to have a variable raised to the 1st power, but they're not linear.
