Problem 2. Measurements of the diameter of spherical plastic beads from the large population of the
beads produced in similar conditions were recorded as three independent data sets. The following
statistics parameters were evaluated: N₁ = 45; d₁ = 8.35 mm; Sa₁ = 0.09 mm; N₂ = 40; d₂
8.33 mm; Sa2 = 0.11 mm; N3 = 38; d3 = 8.4 mm; Sd3 = 0.13 mm. Neglecting systematic errors and
errors other than variation in the measured data set, calculate:
