Step-by-step explanation:
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. (b) For this particular market, the average sale per customer in the deli section is $8.50 with sigma=$2.50. 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, x.
