a)
Interpretation:
The least squares slope and intercept and their standard deviations and the theoretical value has to be calculated.
Concept Introduction:
LINEST:
The LINEST is a Microsoft excel function which is uses the least squares method to measure the statistics for a straight line and array describing that line it is built-in function that can be categorized.
LINEARITY:
It is measure of how well a calibration curve follows a straight line and displaying that the response is proportional to the quantity of the analyte.
Where R means square of
Standard additions to one solution:
The graph can be drawn using the equation
Where X-intercept is
b)
Interpretation:
The standard uncertainty
