We are given that a buyer for a manufacturing plant suspects that his primary supplier of raw materials is overcharging. To determine if his suspicion is correct, he contacts a second supplier and asks for the prices.
The data is given below;
Material Primary supplier Secondary supplier Difference

2 $48 $47 $1
3 $31 $32 -$1
4 $83 $77 $6
5 $37 $37 $0
6 $55 $50 $5
