It is important for you to understand when to use the CLT. If you are being asked to find the probability of the mean, use the CLT for the mean. If you are being asked to find the probability of a sum or total, use the CLT for sums. This also applies to percentiles for means and sums.
Note: If you are being asked to find the probability of an individual value, do not use the CLT. Use the distribution of its random
variable.
