The density of pepsi (actual density= 1.04 g/mL) was analyzed using a buret and a micropipet. The results are presented below.
Buret: 1.0456 g/mL, 1.04364 g/mL, 1.04966 g/mL, 1.04173 g/mL, 1.0392 g/mL
Micropipet: 1.0163 g/mL, 1.027 g/mL, 1.00942 g/mL, 1.01868 g/mL, 1.0262 g/mL
For each tool, calculate the average, sample standard deviation, %RSD, 95% confidence Interval and percent error. Include the units or, after a space, the percent symbol where required.
buret:
average = 1.0439 g/mL
standard deviation = 0.003965 g/mL
%RSD = 0.379884 %
95% confidence Interval = 0.003476 g/mL
% error = 0.381346 %
micropipet:
average = 1.0195 g/mL
standard deviation = 0.007308 g/mL
%RSD = 0.7169 %
95% confidence interval =
% error = 1.9692 %
