Authenticity in Greek restaurants. Refer to the Research in Hospitality Management (September 2019) study of local food and authenticity of restaurants in Greece, Exercise 2.131 (p. 125). Recall that two variables were measured (both on a 10-point scale) for each of nine Greek restaurants: perceived level of traditionalism and perceived level of adaptation to the guests’ tastes. The data are reproduced in the accompanying table, followed by an XLSTAT correlation analysis.

a. Locate and interpret the coefficient of determination, r2 , on the printout.

b. Locate and interpret the coefficient of correlation, r, on the printout.

c. Conduct a test for linear correlation between perceived level of traditionalism and perceived level of adaptation at a = .05. Use the p-value reported on the printout.
