The formula for determining the number of observations needed depends on the level of confidence desired, the standard deviation of the sample observations, and the desired accuracy. The maximum observed value in the sample does not play a role in determining the sample size. The mean of the sample observations may be used to calculate the confidence interval, but it is not a direct factor in determining the sample size.
