The formula to determine the sample size using the formula for the standard error of the mean is n = (z^2 * σ^2) / (E^2), where z is the z-score corresponding to the desired confidence level, σ is the population standard deviation, and E is the desired margin of error. Option C contains the correct formula for determining the sample size using the standard error of the mean. Option A contains an incorrect formula that includes irrelevant variables, and option B contains an invalid character string.
