The State Association of Retired Teachers has recently taken flak from some of its members regarding the poor choice of the association’s name.
The association’s by-laws require that more than 60 percent of the association must approve a name change.

Identify the null and alternative hypothesis that should be tested to determine if a name change is warranted.
