PROBLEM STATEMENT
Find the least weight X such that 90% of the packets produced have weight greater than X

SOLUTION

  • Given, Mean = 0.295 KG, Sigma = 0.025 and Z = (X - Mean)/Sigma 
  • X is on the negative side as per the given statement which states that 90% of the weights are greater. Thereby, remaining 10% of the weights include weight X
  • Using EXCEL function NORM.INV, we can calculate the weight X = .263 KG
