lions [1.4K]

Answer:

Step-by-step explanation:

The sample proportion \hat p = \dfrac{50}{200}

\hat p = 0.25

The null hypothesis and the alternative hypothesis:

H_o: p = 0.20  \\ \\  H_1 : p > 0.20

Thus; the test statistics is:

Z = \dfrac{\hat p - p_o}{\dfrac{p_o(1-p_o)}{n} }

Z = \dfrac{0.25 -0.20}{\sqrt{\dfrac{0.20(1-0.20)}{200} }}

Z = \dfrac{0.05}{\sqrt{\dfrac{0.16}{200} }}

Z = \dfrac{0.05}{\sqrt{0.0008 }}

Z = 1.768

P-value = 2 × P(Z< - 1.768)

From the z tables

P-value = 2 × 0.03853

P-value = 0.07706

Thus, the p-value is 0.05 < P-value < 0.10
