Question

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? -6.131 -5.186 -5.509 --5.649 -5.786 -5.981

Explanation / Answer

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]
