Question
Chapter 25, Problem 25.12QAP
Interpretation Introduction
(a)
Interpretation:
The slope, intercept, regression statistics including the standard deviation about regression should be calculated.
Concept introduction:
Concentration Dopamine take as the dependent variable and Peak current take as the independent viable.
Concentration of Dopamine take to y axis and Peak current take to x axis.
Interpretation Introduction
(b)
Interpretation:
The concentration of dopamine at peak current 2.92 nA should be calculated using the plotted graph.
Concept introduction:
The graph is plotted by taking dopamine concentration as dependant variable and peak current as independent variable.
Therefore, for the given peak current can find the dopamine concentration using the trend line equation.
Interpretation Introduction
(c)
Interpretation:
Standard deviation of the unknown concentration should be calculated.
Concept introduction:
Standard deviation will give that the deviation of the value from the average.
