Please help with this question, thx!! For Question b, you just need to write the correct function for approximate probability

Assume that there are n : 400 customers visiting a. store every day, and that each cus tomer spends a. random amount of money Xi. Furthermore, assume that these amounts are independent and identically distributed with a. Uniform[5,_v 5) distribution. (a) (5 points) Provide an approximate distribution for the average daily customer spend ing (Xn 1 2:1 Xi); specify the distribution's name and parameter values. (1)) (5 points) Find an approximate probability that the total daily customer spending exceeds 11, 500
