For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.)

One passionate salesperson claims that the mean amount its customers spend on cell phone service per month is less than $50.

Was an error made? If so, what type?
A. Yes; Type I error
