I have a question, i don't understand how to use Central limit theorem to find the approximate distribution. The question is: A certain type of bathroom tile is sold in packs of 100 tiles. The distribution of the weights of individual tiles has mean 99 grams and standard deviation 5 grams. (a) Use the central limit theorem to find the approximate distribution of the weight of a pack of 100 tiles. any one can help me.

You have to answer three questions: What is the name of the distribution of the weights? What is the value of the first parameter of this distribution? What is the value of the second parameter of this distribution? Can you answer these?
