You are asked to calibrate a 10 mL vo pipette by weighing to the nearest 0.1 mg the weigh six samples of water delivered by the by dividing by the density of water at 25°C ss of water delivered by the pipette. You weigh six samples of and convert the mass of each to volume by dividing by the densit (0.997048 g/mL). Following are your measurements: 0500 mL. 9.9700 mL, 10.0360 mL, 9.9650 mL, 10.0150 mL. 10.0200 ml Calculate the following statistical measures for this data: Mean(x) = Standard deviation (s) =
Variance (s) = Standard error of the mean (Smean) =
90% confidence interval = 9.9958 +-
(The "true value" of the volume will lie within this interval 90% of the time.)
95% confidence interval = 9.9958 +-
(The "true value" of the volume will lie within this interval 95% of the time.)
