A local basketball team is concerned that the current coach is not training players well. Specifically, they are concerned that the team scored more points per game under the previous coach than under the current one. You offer to analyse their performance under each coach to settle the question. You are given the number of points scored for each game under the previous coach and under the current one:
Current coach 86, 82, 90, 92, 85, 82, 93, 80
Previous coach 120, 45, 100, 80, 54, 108, 67, 54, 112, 43, 86, 90
Is the team performing any differently under the new coach?
