A researcher is interested in the price people would be willing to pay for a spa weekend in the country, compared with the price they would be willing to pay for a spa weekend in the city. The researcher collected data from a random sample of potential spa customers. When he created a histogram of the differences, he noted it was not normal, but was fairly symmetric. The researcher used the Wilcoxon Signed Rank Sum Test Calculations add-in, and produced the output shown in Exhibit 9.47 below.
Is there evidence, at the 5% level of significance, that people are willing to pay more for a spa weekend in the country? The order of subtraction was (price for country spa weekend – price for city spa weekend).
