Objective

Continue procedure from yesterday.

Data

Absorption Spectra

<br.> All peaks at 249nm. <br.>

Calculations and Analysis

Determine the standard deviation for your data points.<br.> Determine the confidence interval for 90% and 95% confidence.<br.> Determine if any data can be ruled out using a Q-test.<br.>

Calibration Curves
