The European Commission recently conducted a survey on passengers’ satisfaction with rail services and discovered that in the case of Bulgarians, 10.1% were very satisfied with the quality of facilities and services, 31.9% were rather satisfied, 29% were rather dissatisfied, and 22.3% were very dissatisfied. Suppose the largest train company in Bulgaria decides to invest considerable time and money to improve the quality of its facilities and services. After using the new policies for a year, company managers want to determine whether the new policy has changed perceptions of the service they offer. They contact 408 of the company’s rail consumers who travelled with the company in the past year and ask them how satisfied they are with the rail services. Fifty-two respond that they are very satisfied. Use a 1% level of significance to test the hypothesis.
