Express the confidence interval 78.9 % < p < 94.9 % 78.9 % < p < 94.9 % in the form of ˆ p ± M E p ^ ± M E . % ± ± %
Values are given as,
Lower limit = 78.9%
Upper limit = 94.9%
Calculating sample proportion:
=
(upper limit +lower limit)/2
= (94.9+78.9)/2
= 173.8/2
= 86.9%
Calculating margin of error :
E = (upper limit - lower limit)/2
= (94.9-78.9)/2
= 16/2
= 8%
Calculating confidence interval :
CI= 86.9%
