Question

Geologists have successfully used statistical models to evaluate the nature of sedimentary deposits (called facies) in reservoirs. One of the models’ key parameters is the proportion P of facies bodies in a reservoir. An article in Mathematical Geology (Apr. 1995) demonstrated that the number of facies bodies that must be sampled to estimate P satisfactorily is approximately normally distributed with μ = 99 and σ = 4.3. How many facies bodies are required to estimate P satisfactorily for 99% of the reservoirs evaluated?
