Question

Express the confidence interval

left parenthesis 0.008 comma 0.096 right parenthesis(0.008,0.096)

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 = = (0.008+0.096)/ 2=0.052

Margin of error = E = Upper confidence interval - = 0.096-0.052=0.044

In the form of :

- E < p < + E is,

0.052-0.044 < p <0.052+0.044

0.008<p<0.096
