A Small Private College Is Interested in Determining the Percentage $\mathrm { H } _ { 0 }$

A small private college is interested in determining the percentage of its students who live off campus and drive to class. Specifically, it was desired to determine if less than 20% of their current students live off campus and drive to class. Find the large-sample rejection region for the test of interest to the college when using a level of significance of 0.01.

A) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { z } < - 1.28$ .
B) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { z } < - 1.96$ .
C) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { z } < - 2.33$ or $\mathrm { z } > 2.33$ .
D) Reject $\mathrm { H } _ { 0 }$ if $\mathrm { z } < - 2.33$ .
