Question

Identify the two types of incorrect decisions in a hypothesis test. For each incorrect​ decision, what symbol is used to represent the probability of making that type of​error?

Choose the correct answer below.

A.A Type I error is accepting a false null​ hypothesis, whose probability is denoted

alphaα.

A Type II error is not accepting a true null​ hypothesis, whose probability is denoted

betaβ.

B.A Type I error is not rejecting a false null​ hypothesis, whose probability is denoted

alphaα.

A Type II error is rejecting a true null​ hypothesis, whose probability is denoted

betaβ.

C.A Type I error is rejecting a true null​ hypothesis, whose probability is denoted

alphaα.

A Type II error is not rejecting a false null​ hypothesis, whose probability is denoted

betaβ.

D.A Type I error is not accepting a true null​ hypothesis, whose probability is denoted

alphaα.

A Type II error is accepting a false null​ hypothesis, whose probability is denoted

betaβ.

Answer 1

Type I error is associated with rejecting the true null hypothesis and denoted with $\alpha$.

Type II error is associated with not rejecting the false null hypothesis and denoted with $\beta$.

Option C is correct.
