Express the confidence interval
(0.055,0.147)
in the form of
Modifying Above p with caret minus Upper E less than p less than Modifying Above p with caret plus Upper Ep−E<p<p+E.
Solution :
Point estimate = = (Lower confidence interval + Upper confidence interval ) / 2
Point estimate = = (0.055+0.147) / 2=0.101
Margin of error = E = Upper confidence interval - = 0.147-0.101=0.046
In the form of :
- E < p < + E is,
0.101-0.046< p <0.101+0046
