A tape manufacturer has created a new formula that is supposed to be more adhesive on all types of surfaces. Managers wish to conduct an experiment on aluminum and wood to see how well the tape sticks to them. To determine this, they take a random sample of tape with the new formula and use four different weights taped to random places on each of the two surfaces. They will measure how long the tape holds the weights on each surface and compare the times. Which of the following best describes this experiment?
A. This is an observational study.
B. This is an experiment with blocking.
C. The type of surface is a confounding variable.
D. This is a double-blind experiment.
E. This is a randomized experiment resulting in the placebo effect.
