(p.125). Recall that a sample of 9 Greek restaurants participated in the study. Based on interviews with the restaurant managers, two variables were measured (each on a 10-point scale): perceived level of traditionalism and perceived level of adaptation to the guests’ tastes. The data are reproduced in the next table.

a. Use a 99% confidence interval to estimate the average level of traditionalism at all Greek restaurants. Interpret the result.

b. Use a 99% confidence interval to estimate the average level of adaptation at all Greek restaurants. Interpret the result.

c. Would you be surprised if the true average level of traditionalism at all Greek restaurants equals 2? Explain.

d. Would you be surprised if the true average level of adaptation at all Greek restaurants equals 2? Explain.
