A student researcher developed a novel analytical method for determining the lead (Pb2+) content in waste water. To demonstrate the efficacy of the new method, the researcher measured the Pb2+ concentration in an unknown sample using the novel method (Method 1). She then measured the same sample using the standard, conventional analytical method (Method 2). The results of this experiment are shown as the mean (x) and standard deviation (s) of the Pb2+ concentration in parts per million (ppm). The number of replicate measurements (n) is also given. Method 1: x1=3.600ppms1=0.220ppmn1=6 Method 2: x2=3.750ppms2=0.170ppmn2=6 Calculate the F value. Fcalc= Are the standard deviations significantly different from each other at the 95% confidence level? The value of Ftable can be found in the table of critical F values. no yes Calculate the value of tcalctocomparethedatasetsfromMethod1andMethod2. Can the student researcher assert that the new analytical method be considered a replacement for the conventional method with 99% confidence? A list of t values can be found in the Student's t table. no
