In its ninth year, the Barclaycard Business Travel Survey has become an information source for business travelers not only in the United Kingdom but internationally as well. Each year, as a result of the research, Barclaycard Business has been able to predict and comment on trends within the business travel industry. One question asked in the 2003/2004 and 2004/2005 surveys was, “Have you considered reducing hours spent away from home to increase quality of life?” The following table represents the responses:

2003/2004 2004/2005 Total Yes—have reduced 400 384 784 Yes—not been able to 400 300 700 No—not certain 400 516 916 Total 1200 1200 2400

a. Determine if the response to the survey question was independent of the year in which the question was asked. Use a significance level of 0.05.

b. Determine if there is a significant difference between the proportion of travelers who say they have reduced hours spent away from home between the 2003/2004 and the 2004/2005 years.
