In the manufacturing process of a pharmaceutical product, repeated measurements of the concentration of the active ingredient follow a Normal distribution with mean u equal to the true product concentration, and with standard deviation = 0.008 g/l. How many measurements would be needed to estimate the true concentration within ±0.001 g/l with 95% confidence? Give your answer rounded up to the nearest whole number. n=
