Lesson2 worksheet

Procedure

Using their information from lesson1worksheet.doc, the students will use lesson2worksheet to calculate the threshold for a given number of devices, false acceptance rates, false rejection rates, the time it would take to admit the number of fans, how many devices would be needed and the cost to implement their mode of security.  The students will then organize data and make graphs using Excel to compare and analyze data to arrive at a final consensus about which biometric security mode their company will employ.
