$1.$ Determine the minimum and maximum inventory levels. $2.$ Determine the minimum and maximum daily sales. $3.$ Determine the number of occurrences of each inventory level. One way is to use np$.$unique function. $4.$ Compute the frequency $($probability$)$ of each inventory level. $5.$ Compute the probability that the inventory level is greater than $15.6.$ Compute the expected inventory level. $7.$ Compute the expected inventory holding cost per year $($based on beginning of day inventory$)$ if the inventory carrying cost is $15\%$ per year and the average cost of an item is $$22\mathrm{.}50.8.$ Compute the expected sales per day. $9.$ How many days were there potentially lost sales due to insufficient inventory?
