By measuring the absorbance readings of a set of McFarland standards construct a standard curve in Excel of bacterial cell concentration mL versus absorbance at 600 nm In addition Marco has applied linear regression analysis to their data to produce a trendline and an R value of the line of best fit see Marco s standard curve below Given these results if Marco measured an undiluted bacterial sample and obtained an absorbance reading of 0 17 what would be the expected bacterial cell concentration of that sample Show all work use scientific notation in the format a aa 10 and make sure to include the appropriate units 3 pts Marco s Standard Curve of Bacterial Concentration Versus Absorbance Average Absorbance at 600 nm 0 5 0 45 0 4 0 35 0 3 0 25 0 2 0 15 0 1 0 05 0 0 00E 00 2 00E 08 Mahar 04b l 4 00E 08 6 00E 08 Bacterial Cells mL 8 00E 08 y 3E 10x 0 0088 R 0 9986 1 00E 09 1 20E 09 1 40E 09 Bon em
