Question

Express the confidence interval left parenthesis 0.057 comma 0.139 right parenthesis in the form of ModifyingAbove p with caret minus Upper E less than p less than ModifyingAbove p with caret plus Upper E. ____less than p less than ____ ​(Type integers or​ decimals.)

Answer 1

Solution :

Given that,

Lower confidence interval = 0.057

Upper confidence interval = 0.139

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

= (0.057 + 0.139) / 2

= 0.196

= 0.098

Margin of error = E = Upper confidence interval - = 0.139 - 0.098 = 0.041

In the form of :

- E < p < + E is,

0.098 - 0.041 < p < 0.098 + 0.041
