Which of the following calculations is NOT derived from the confidence interval?

A. The point estimate of µ, x overbarxequals=StartFraction (upper confidence limit )plus (lower confidence limit )Over 2 EndFraction (upper confidence limit)+(lower confidence limit) 2
B. The margin of error, Eequals=StartFraction (upper confidence limit )minus (lower confidence limit )Over 2 EndFraction (upper confidence limit)−(lower confidence limit) 2
C. Difference between the limits, 2Eequals=(upper confidence limit )minus (lower confidence limit )(upper confidence limit)−(lower confidence limit)
D. The population mean, muμequals=(upper confidence limit )plus (lower confidence limit )(upper confidence limit)+(lower confidence limit)
