The laboratory supervisor of a commercial lab is given the responsibility of purchasing cuvettes for their spectrophotometer. They settle on two suppliers whose cuvette prices are the same. The supervisor asks a lab tech to test random samples of cuvettes for their absorbance values of a known concentration of the solution. The tech selects 5 random cuvettes from each supplier and reports the following values: Supplier A 0.155 0.163 0.157 0.164 0.165 The actual absorbance is 0.1613. Report the mean for each of the suppliers with the proper number of significant figures. (0.5pts) Supplier A (0.5pts) Supplier B Supplier B 0.151 0.163 0.165 0.170 0.155 What is the percent error for each supplier's mean?

Answer rating: 100% (QA)

To calculate the mean absorbance for each supplier we sum up the absorbance values and divide by the ... View the full answer
