Two different design configurations are being considered for a new component. There are three possible reasons for failure of the component. An engineer wishes to determine whether there is a relationship between the design and the reason for failure.
Question: use an appropriate test to determine if the reason for component failures is independent of their designs. Show your manual calculations here.
Reason 1 Reason 2 Reason 3
Design A 15 11 10
Design B 15 21 19
