Absorption rates into the body are important considerations when manufacturing a generic version of a brand-name drug. A pharmacist read that the absorption rate into the body of a new generic drug (G) is the same as its brand-name counterpart (B). She has a researcher friend of hers run a small experiment to test H₀: μ_G - μ_B = 0 against the alternative H_A: μ_G - μ_B ≠0. Which of the following would be a Type I error?

▸ Deciding that the absorption rates are different, when in fact they are not.

▸ The researcher cannot make a Type I error, since he has run an experiment.

▸ Deciding that the absorption rates are different, when in fact they are.

▸ Deciding that the absorption rates are the same, when in fact they are.

▸ Deciding that the absorption rates are the same, when in fact they are not.
