The purpose of subjecting your BSA protein standard plot data to the least squares statistical method was to
a. determine intuitively the best fit straight line.
b. statistically determine the best straight line through a series of experimental points.
c. determine the overall shape of the BSA standard curve.
d. determine the protein concentration in the unknown samples.
Solutions
Expert Solution
B - statistically determine the best line through a series of experimental points.
BSA standard plots are generally used to determine the concentration of protein sample.This is achieved by ploting responses of standards and determining the best fitting line between them. Using the absorbance values of unknown sample, the protein concetration is determined by the formula for the standard line.

Plot MATINGS by AGE, then add a least squares line. Include your
plot.
Is there evidence that modeling matings using a linear
regression with age might not be appropriate? Explain. (Hint: Check
for a linear trend and for constant variance about the linear
fit.)
