Question: Geologists have successfully used statistical models to evaluate the nature

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?
