5. In the sample of synthesized gold nanoparticles, the particle diameter is distributed approximately normally, with the arithmetic mean x and the standard deviation s indicated in the table below for the corresponding problem number. Calculate (for your problem number) the proportion of particles in the sample whose diameters are between x1 and x2, assuming µ= x and σ=s.
