r-ruslan [8.4K]

Answer:

The Point estimate of the Population proportion E = 0.039≅0.04

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 992

and x = 570

The Population proportion

$p = \frac{x}{n} = \frac{570}{992} = 0.5745$

Step(ii):-

The point estimate of the Population proportion is determined by

$E = 2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }$

E = 0.039≅0.04

Final answer:-

The point estimate of the Population proportion E = 0.039≅0.04
