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.

Control Chart Drawing Assignment
The table below provides the number of alignment errors observed during the final inspection of
a certain model of airplane. Calculate the central, upper, and lower control limits for the c-chart
and draw the chart precisely on the graph sheet provided (based on 3-sigma limits).
Your chart should include a line for each of the control limits (UCL, CL, and LCL) and the
points for each observation. Number the x-axis 1 through 25 and evenly space the numbering for
the y-axis. Connect the points by drawing a line as well. Label each line drawn.

Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask.
