Question

Find the critical value and rejection region for the type of z-test with level of significance α $\alpha _ { 2 }$ Right-tailed test, α $\alpha$ = 0.01
A) $z _ { 0 } = 2.33 ; z > 2.33$
B) $z _ { 0 } = 2.575 ; z > 2.575$
C) $z _ { 0 } = 1.645 ; z > 1.645$
D) $\mathrm { z } _ { 0 } = 1.96 ; ; \mathrm { z } > 1.96$

Quizplus · Accepted Answer

For a right-tailed test with α = 0.01, the critical value is 2.33, and the rejection region is z > 2.33.
