How To Calculate J Coupling . The j coupling (distance between lines in a quartet for instance) is a constant value in hz. Where j, the polar second moment of intertia is: Figures from www.orgchemboulder.com Estimation of the j magnetic exchange coupling using the gga+u method. I would like to ask another question herein. Here is how you calculate a coupling constant j:

Two sample proportion test is used to determine whether the proportions of two groups from different samples differ. In this example you are given the standard deviations for each sample thus you need to take the square of the standar deviations to find the variances: Proportion 2 = n2 / n2.
