You conduct a poll. You ask 1038 if the support the candidate and 428 claim they support. Conduct a test of hypoth that the candidates true rate of support in community is 0.5 against the alternate against alternate that it\'s not 0.5. What is test statistic?

Solution
Formulating the null and alternatuve hypotheses,
Ho: p = 0.5
Ha: p =/= 0.5
As we see, the hypothesized po = 0.5
Getting the point estimate of p, p^,
p^ = x / n = 0.412331407
Getting the standard error of p^, sp,
sp = sqrt[po (1 - po)/n] = 0.015519271
Getting the z statistic,
z = (p^ - po)/sp = -5.649014783 = -5.649 [OPTION D]
