Please help to answer the following question

A bank holds the mortgage on a motel which the motel owner says has an average daily revenue of at least $2048. In the event the average is not at least $2048, the bank will ask the motel owner for additional collateral for the loan as protection against loan default. A loan officer is aware that the daily average revenue is normally distributed and randomly selects 20 days during the last six months. The sample has a mean of $2003 and standard deviation of $144.00. At the 0.01 level, is the bank loan financially sound (should the bank ask for additional collateral)?
