Question: A fishing line is being manufactured by two processes to determine if there is a difference in the mean breaking strength of the lines. 10

A fishing line is being manufactured by two processes to determine if there is a difference in the mean breaking strength of the lines. 10 pieces by each process are selected and then tested for breaking strength. The results are as follows. Use the rank-sum test with ? = 0.1 to determine if there is a difference between the mean breaking strengths of the lines manufactured by the two processes. 10.4 9.6 10.9 8.7 9.8 9.8 11.5 11.8 9.8 9.9 Process 1

10.4 9.6 10.9 8.7 9.8 9.8 11.5 11.8 9.8 9.9 Process 1 10.0 9.9 9.3 10.7 Process 2 10.8 9.9 11.2 10.1 10.5 11.0 9.8 9.5
