WebbCalculate the two z-scores for the percentages given - I use tables, and get for 3cm that the z-score is -0.84, and for 8cm the z-score is 1.28. Set up two simultaneous equations 8 - mu = 1.28 x sigma and 3 - mu = -0.84 x sigma. Subtract one equation from the other to eliminate mu: 2.12 x sigma = 5, so sigma = 2.36. Solve for mu = 4.98.
