Ainat [17]

Answer:

The test statistic Z = 3.125

Step-by-step explanation:

<em>Given Population proportion P = 0.25</em>

<em>Given sample size 'n' = 696</em>

<em>Sample proportion 'p⁻' = 0.30</em>

Test statistic

$Z = \frac{p^{-} -P}{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.30-0.25}{\sqrt{\frac{0.25 X 0.75}{696} } } = 3.125$

<u><em>Final answer</em></u>:-

The test statistic Z = 3.125
