(Round to three decimal places as needed.)​

Answer 1

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

Explanation:

Step(i):-

Given that the sample size 'n' = 992

and x = 570

The Population proportion

`p = (x)/(n) = (570)/(992) = 0.5745`

Step(ii):-

The point estimate of the Population proportion is determined by

`E = 2.576 (√(0.574(1-0.574)) )/(√(992) )`

E = 0.039≅0.04

Final answer:-

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