1) What is the exact mathematical relationship between the width of a confidence interval and the Maximum Error of Estimate?

2) In your own words, describe the relationship between the standard error and maximum error. You may use the formulas for each in your explanation.

Solution

The width of the interval is two times the max error of estimate

ME = z*(std) where z depends on the level of confidence

2)

standard error is the standard deviation
maximum error is the product of the std and the z or t value
associated with the degree of confidence.
