During an eight-hour production run, 1 000 000 Onion capsules are made. We want to determine the average mass of Allicin in the Onion capsules. Since half the masses will be above the average and half below, we will use a probability of 0.5. How many capsules must be tested during this eight-hour production run, such that the average sample mass will be within 5 % of the true average population mass?
