The right solution is "-8.25".

Step-by-step explanation:

The given values are:

Sampled people,

n = 150

Null and alternative hypotheses will be:

$H_0:p=0.53$

$Ha:p\neq 0.53$

The z-statistics will be:

⇒ $z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }$

On substituting the values, we get

⇒ $=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }$

⇒ $=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }$

⇒ $=\frac{-0.33}{0.04}$

⇒ $=-8.25$
