Question
"My careful physical examination shows no evidence of any serious
problem," said Doctor Morpheus. "However, a very costly lab test can be
performed to check for the rare condition known as estomalgia fatalis. The
test is almost invariably negative for persons with your age and symptoms.
My personal hypothesis is that the occasional stomach pain you reported is
due to indigestion caused by eating tacos with too much hot sauce. But you
must decide for yourself." As you consider your doctor's hypothesis, what
would be the consequence of Type I error on your part?
Select one:
a. Can't be determined without knowing the type of test
b. Your estomalgia fatalis will go undetected
c. You will waste money on an unnecessary lab test
d. Your survivors will enjoy a sizeable malpractice award
Explanation / Answer
A type I error is incorrectly rejecting a true null hypothesis.
Thus you have decided you might have the disease, when in fact you don't have. That means you had the test, but it was a waste of money because it was unnecessary.
Hence,
OPTION C: You will waste money on an unnecessary lab test [ANSWER]
