Think about the situation where you are investigating the relationship of study time vs. exam grade.a. Which variable would be on the x-axis (and why)?b. Which variable would be on the y-axis (and why)?c. Would you expect the slope to be positive or negative (and Why)? 2) Contrast and compare interpolation with extrapolation. Which is “safer” to use and why?3) Look up how “the best fit straight line” is constructed. The term “Least squares” should be in your explanation.4) If I plot some data and end up with a r2 of (-) 0.99, is my plot useless? Explain.
The spectrophotometer is set at 600 nm. The absorbance of each cuvette is read. The data is shown below: Cuvette 1 is the clank Cuvette # ml albumin Absorbance 0. 0.2 .063 3 0.4 .163 4. 0.6 .187 0.8 .253 1.0 .289 Using this data, plot an Excel graph showing absorbance (y-axis) vs ml albumin (x-axis). Find the correlation coefficient (r). R2 > 0.99 = excellent data; r2 0.98-0.95 good data r2 0.94 -0.90 = fair data. How would you describe this data?- To find the relative sensitivity, for each of tubes 2-6 (neglect blank), perform the following operation absorbance (Lowry)/Absorbance (Biuret x 0.5 gram albumin (Biuret)/0.05 gram (Lowry) x 200 ml (Lowry)/100 mL (Biuret). This implifies to Relative sensitivity = 20 dilution factor x absorbance (Lowry)/Absorbance (Biuret). Report your relative sensitivity as an average of all 5 values.
