(b) In an experiment to compare the bond strength of two different adhesives, each adhesive was used in five bonding of two surfaces, and the force (in Pa) necessary to separate the two surfaces was determined for each bonding, resulting in the following data shown in Table Q1(b). Decide whether the true average bond strength is differed for the two adhesives by using the Mann-Whitney Test. Use significant level of 0.05.
