Absorption rates into the body are important factors 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: μG - μB = 0 against the alternative HA: μG - μB ≠ 0. Which of the following would be a Type I error?
A) Deciding that the absorption rates of G are higher, when in fact they are not.
B) Deciding that the absorption rates of G are lower, when in fact they are not.
C) Deciding that the absorption rates are the same, when in fact they are not.
D) Deciding that the absorption rates are different, when in fact they are not.
E) Deciding that the absorption rates are the same, when in fact the absorption rates of G are higher.

A Type I error occurs when the null hypothesis is rejected when it is actually true. In this scenario, rejecting the null hypothesis (H0: μG - μB = 0) means deciding that the absorption rates are different when, in fact, they are not.
