Chapter 4: Q28P (page 93)

Set up a spreadsheet to reproduce Figure 4-15. Add error bars: Follow the procedure on pages 87-88. Usesyfor the + and - error.

Short Answer

Expert verified

A spreadsheet similar to Figure 4-15is set up in step 2.

A graph plotted on the spreadsheet by the use of x and y values is shown in step 3.

Step by step solution

01

Error bar to agraph

Error bars on the graphs helps to judge the quality of data and the fit of a curve to the data.

02

Generation of Spreadsheet

Given data:

Use the data from Figure 4-15

Use the procedure from pages 87-88to add error bars.

Use syfor the + and - error

A spreadsheet similar to Figure 4-15 is as shown below.


The above spreadsheet gives the slope, the intercept and its uncertainties, and also the standard uncertainty and standard deviation ofysy

03

Plot the graph

Now, let us plot a graph on the spreadsheet by the use of the x and y values.

The error bars on the points of the graph are drawn with the help of the procedure given in pages 87-88.

The obtained graph with the addition of error bars is shown in Figure 2.

List the three different cases that we studied for comparison of means, and write the equations used in each case.

What fraction of vertical bars in Figure 4-5a is expected to include the population mean (10000) if many experiments are carried out? Why are the 90 % confidence interval bars longer than the 50 % bars in Figure 4-5?

Excel LINEST function. Enter the following data in a spreadsheet and use LINEST to find slope, intercept, and standard errors. Use Excel to draw a graph of the data and add a trendline. Draw error bars of±syon the points.

Two methods were used to measure fluorescence lifetime of a dye. Are the standard deviations significantly different? Are the means significantly different?

Logarithmic calibration curve. Calibration data spanning five orders of magnitude for an electrochemical determination of p-nitrophenol are given in the table. (The blank has already been subtracted from the measured current.) If you try to plot these dataon a linear graph extending from 0 to 310μg/mLand from 0 to 5260nA, most of the points will be bunched up near the origin. To handle data with such a large range, a logarithmic plot is helpful.

(c) Find the concentration of p-nitrophenol corresponding to a signal of 99.9nA.

(d) Propagation of uncertainty with logarithm. For a signal of 99.9nA, log (concentration) and its standard uncertainty turn out to be 0.68315±0.04522. With rules for propagation of uncertainty from Chapter 3, find the uncertainty in concentration.
