use the given confidence interval limits to find the point e

Solution

for example:

0.772 is less than p and p is less than 0.776

The point estimate is the average of the confidence interval limits:

p-hat = (0.772+0.776)/2 = 0.774

Margin of Error = 0.776-0.774/ 2 = 0.001

(p-e, p+e)

[0.773, 0.775]
