Can I have some help with this

The total daily sales, S, in the deli section of a supermarket is the sum of the purchases made by customers on a given day. (a) What kind of probability distribution do you expect the total daily sales to have? Explain. Because the total daily sales is a ---Select--- a of random variables, the distribution will ---Select--- 6 according to the Central Limit Theorem. (b) For this particular market, the average purchase per customer in the deli section is $7.50 with a' = $1.50. If 30 customers make deli purchases on a given day, give the mean and standard deviation of the probability distribution of the total daily sales, 5. (Round your answers to the nearest cent.) mean $ standard deviation $
