There is 10 rain gauge stations in a catchment. The annual rainfalls recorded by the gauges are the following: 102.3cm, 181.12cm 123.4cm, 43.5cm, 112.23cm, 88.89cm, 75.5cm, 69.69cm, 97.87cm, 111.11cm. For an 8% error in the estimation of mean rainfall, calculate the optimum number of stations in the catchment.
