B) $ H_{0}: p=0.28 $ and $ H_{A}: p<0.28 $
C) $ H_{0}: p=0.28 $ and $ H_{A}: p \neq 0.28 $
D) $ H_{0}: p \neq 0.28 $ and $ H_{A}: p=0.28 $

Quizplus · Accepted Answer

The null hypothesis $ H_{0}: p=0.28 $ assumes that the proportion of people having difficulty making mortgage payments in these cities is the same as the national average. The alternative hypothesis $ H_{A}: p>0.28 $ suggests that the problem is more severe in these cities, meaning the proportion is greater than 0.28.
