We Conduct a Significance Test with H0: P = 0 $z=0.43 \pm 1.96 \sqrt{\frac{0.43-0.57}{230}}$

Multiple Choice

We conduct a significance test with H0: p = 0.43 and Ha: p × 0.43. We take a sample of size 250 and get a sample proportion of 0.40. The appropriate test statistic is:

A) $z=0.43 \pm 1.96 \sqrt{\frac{0.43-0.57}{230}}$

B) $z=\frac{0.40-0.43}{\sqrt{\frac{0.43 \cdot 0.57}{250}}}$

C) $z=0.40 \pm 1.96 \sqrt{\frac{0.40 \cdot 0.60}{250}}$

D) $z=\frac{0.40-0.43}{\sqrt{\frac{0.40-0.60}{250}}}$

E) $z=\frac{0.43-0.40}{\sqrt{\frac{0.40-0.60}{250}}}$
