Q: In one of the ethnically diverse areas of a large city, a branch manager of a local bank has been receiving complaints from the clients about staff behavior. He has decided to introduce a training program for his staff, and has retained the services of a human resources consultant. Over a weekend, the consultant has invited representatives of various ethical organizations to participate in a discussion session. In addition, the consultant has shown a documentary about the multicultural nature of Canadian society. Following the completion of the training program, the manager claims a reduction in the number of complaints. Results are shown below:
Individual Before Training After Training
1 92 85
2 88 83
3 84 78
4 89 79
5 85 83
6 90 87
7 91 93
At a 0.05 level of significance, test the hypothesis that the training program has successfully reduced the rate of complaints.
