Question

Express the confidence interval (0.054, 0.110 ) in the form of ModifyingAbove p with caret minus Upper E less than p less than ModifyingAbove p with caret plus Upper E.

_________< p< _______________​(Type integers or​ decimals.)

Answer 1

Solution :

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

Point estimate = = (0.054+0.110) / 2=0.082

Margin of error = E = Upper confidence interval - = 0.110-0.082=0.028

In the form of :

- E < p < + E is,

0.082-0.028 < p <0.082+0.028
