WebMar 25, 2024 · The test statistic is calculated as z = (x – μ) / (s/√n) Thus, we can solve this equation for the sample mean: x = μ – z* (s/√n) x = 500 – 1.645* (24/√100) x = 496.05 Step 3: Find the probability of the minimum sample mean actually occurring. We can calculate this probability as: P (Z ≥ (496.05 – 490) / (24/√100)) P (Z ≥ 2.52) WebHomogeneity testing • Comminute and mix bulk material. • Split into distribution units. • Select m>10 distribution units at random. • Homogenise each one. • Analyse 2 test portions from each in random order, with high precision, and …
