Question

Express the confidence interval left parenthesis 0.082 comma 0.136 right parenthesis in the form of ModifyingAbove p with caret minus Upper E less than p less than ModifyingAbove p with caret plus Upper Ep−E<p<p+E.

Answer 1

Solution :

Point estimate = = (Lower confidence interval + Upper confidence interval ) / 2

Point estimate = = (0.082+0.136) / 2=0.109

Margin of error = E = Upper confidence interval - = 0.136-0.109=0.027

In the form of :

- E < p < + E is,

0.109-0.027 < p <0.109+0.027
