Express the confidence interval 0.666<p<0.888 in the form DIE +E=0+0

Question:

Express the confidence interval 0.666<p<0.888 in the form DIE +E=0+0

Express the confidence interval 0.666<p<0.888 in the form DIE +E=0+0

Answers

Solution :

confidence interval = 0.666 < p <0.888

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

Point estimate = \hat p = (0.666 + 0.888) / 2

Point estimate = \hat p = 0.777

Margin of error = E = Upper confidence interval - \hat p

Margin of error = E = 0.888 - 0.777

Margin of error = E = 0.111

in the form  \hat p ± E   

= 0.777  ± 0.111
