One hundred School children spent the day at Wally World, a poplar amusement park. Parents gave each child $20 for food, with orders to return the unspent funds at the end of the day. The lemon-lime gelato at the concession stand is quite popular with children, and, in fact, the children found no other item of food worth buying. A survey conducted on the bus on the way home revealed that children bought a mean of 2.3 gelatos, with a standard deviation of 0.6 gelatos. If a gelato sells for $2.50, find the sample mean and sample standard deviation for the amount of unspent money returned at the end of the day.
