Answer:

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

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the sample size 'n' = 992

  and                                     x = 570

The Population proportion

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

<u><em>Step(ii):-</em></u>

<u><em>The point estimate of the Population proportion is determined by</em></u>

<u><em></em></u>E =   2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }<u><em></em></u>

E = 0.039≅0.04

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

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

<u><em></em></u>
