Question

Express the confidence interval (82.5%, 95.9%) in the form of p̂ +/- ME

Answer 1

The confidence interval (82.5%, 95.9%) can be expressed in the form of p̂ +/- ME as follows:

p̂ = 0.889 (point estimate)

ME (margin of error) = (95.9% - 82.5%)/2 = 6.7%

Therefore, the confidence interval can be expressed as:

p̂ +/- ME = 0.889 +/- 0.067
