The 95% confidence limit for calcium in control sera is reported as 9.2-10.2 mg/dl. Calculate the value for one standard deviation and the coefficient of variation for this data.

**Maranda**, Monday, January 21, 2013 at 8:27pmI might have figured it out and it was easier than I though it was if I'm correct.

Does this look right?....

Lower Limit = mean - 2SD

and

Lower Limit = 9.2 mg/dl

9.2 = ((9.2+10.2)/2) - 2SD

2SD = 0.5

SD = 0.25??
