Problem: A CEM 262 student determined the concentration of calcium in a solution using gravimetric analysis. The following concentrations were determined in the five trials: 6.060 g/L, 6.015 g/L, 6.012 g/L, 6.064 g/L, and 6.025 g/L. Use these values to answer the next six questions. Except where noted, report values with units.

What is the mean value for this data set?

What is the standard deviation of this data?

What is the variance of this data?

What is the RSD for this data? Please enter the numerical value for RSD without units.

(The correct unit for RSD is ppt (parts per thousand), however currently CAPA is not recognizing ppt as a unit.)

Based upon this data, at the 95% confidence level the true concentration (population mean) is expected to be between what two values?

Maximum concentration?

Minimum concentration?
