Problem 14-27 (Algorithmic) A perishable dairy product is ordered daily at a particular supermarket. The product, which costs $1.2 per unit, sells for $1.64 per unit. If units are unsold at the end of the day, the supplier takes them back at a rebate of $1 per unit. Assume that daily demand is approximately normally distributed with µ = 145 and ? = 30. What is your recommended daily order quantity for the supermarket? If required, round your answer to two decimal places. Q* = What is the probability that the supermarket will sell all the units it orders? If required, round your answer to four decimal places. P(Stockout) = In problems such as these, why would the supplier offer a rebate as high as $$1? For example, why not offer a nominal rebate of, say, 25¢ per unit? What happens to the supermarket order quantity as the rebate is reduced? The higher rebate the quantity that the supermarket should order.

Last week, 108 cars received parking violations in the green parking lot. Of these, 27 had unpaid parking tickets from a previous violation. Assuming that last week was a random sample of all parking violators, find the width of the 90 percent confidence interval for the percentage (correct to four decimal places) of parking violators that have prior unpaid parking tickets.

A spring loaded piston cylinder contains 1.5 kg of air at 27°C and 160 kPa. It is
now heated in a process where pressure is linear in volume, P = A + BV, to twice the
initial volume where it reaches 900 K. Find the work, the heat transfer and the total
entropy generation assuming a source at 900 K. Is this a possible process?
