vesna_86 [32]

Answer:

p = 0.52392

Step-by-step explanation:

Here we have

p = 23% = 0.23

\hat p = 208/800 = 0.26

n = 800

q = 1-p = 0.77

α = 5% = 0.05

Here we have

Z test given by

z=\frac{\hat{p}-p}{\sqrt{\frac{pq}{n}}}

From which we have

From the Cpdf we have Probability = 0.0219, z = 2.016

Therefore from the z score = 0.0683, p = 0.52392 from z table.
