A public opinion survey investigated whether a majority (more than 50%50\%50%50, percent) of adults supported a tax increase to help fund the local school system. A random sample of 200200200200 adults showed that 113113113113 of those sampled supported the tax increase.
Researchers used these results to test H0:p=0.5H_0:p=0.5H0β:p=0.5H, start subscript, 0, end subscript, colon, p, equals, 0, point, 5 versus Ha:p>0.5H_\text{a} : p>0.5Haβ:p>0.5H, start subscript, start text, a, end text, end subscript, colon, p, is greater than, 0, point, 5, where is the true proportion of adults that support the tax increase. They calculated a test statistic of zβ1.84z\approx 1.84zβ1.84z, approximately equals, 1, point, 84 and a corresponding P-value of approximately 0.0330.0330.0330, point, 033.
