:p=0.5H, start subscript, 0, end subscript, colon, p, equals, 0, point, 5 versus H_\text{a} : p>0.5H
a

:p>0.5H, start subscript, start text, a, end text, end subscript, colon, p, is greater than, 0, point, 5, where ppp is the true proportion of adults that support the tax increase.
Which of the following represents the P-value for their test?
