Answer: A. z = -2.57

Step-by-step explanation:

Let p be the population proportion of people polled favor the incumbent.

As per given , we have

H_0: p=0.54\\\ H_a: p

Sample size : n= 1030

sample proportion :  \hat{p}=0.50

Test statistic for proportion : z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

z=\dfrac{0.50-0.54}{\sqrt{\dfrac{0.54(1-0.54)}{1030}}}\\\\= \dfrac{-0.04}{\sqrt{\dfrac{0.2484}{1030}}}\\\\=\dfrac{-0.04}{0.015529488}\approx-2.57

Hence, the  test statistic is z = -2.57 .

Thus , the correct answer is A. z = -2.57 .
