Plot theresult. Be sure to show the data POINTS as well as the linear regression model, theequation for the linear regression result, and the R2 value for the resulting fit.Use the LINEST function in Excel to learn the concentration of the analyte solution.Use the error in the intercept as your basis for determining the 95% confidenceinterval in error associated with the intercept result. (Note, the output from LINESTis $/ nC.d. Report the concentration of your unknown sample with a 95% confidence interval.3. The answer in 2d should reflect a dilution step taken in the procedure necessary for preparingthe samples. This dilution step involves using two pieces of glassware: A 25.0 mL volumetricpipet and a 100 mL volumetric flask. Using the error in the intercept determined in 2c as yourbasis for the error in your sample, propagate the error accumulated by using class A glasswarefor preparing the sample for analysis. Report the tolerance directly with the calculatedconcentration confidence interval.4. A 50 mL graduated cylinder typically has a tolerance of 1 mL. A 100 mL beaker can be used toabout +5 mL. A general chemistry student decided that the volumetric glassware was toomuch work, so they made their sample solution using a beaker and 50 mL graduated cylinderrather than the more precise, volumetric glassware. Propagate the error for this secondscenario. Make a quantitative argument for whether or not using volumetric glassware is thebest practice for measuring accurate folumes.5. Answer the Challenge Questions in your notebook.

The error propagation during the dilution process is to be calculated.
