Chapter CR, Problem 18E

Olympic medals. Over the course of the modern Olympics, France, Italy, and Great Britain have participated in roughly the same number of Olympic games. But is the distribution of their medals the same, or do they differ? Here is a table summarizing their Summer Olympic performances:

Chi-square = 9.505 with 4 df

P-value = 0.0497

1. a) State and test an appropriate hypothesis using the chi-square value reported here. Be clear about the type of test you are performing.
2. b) State your conclusion from that test.
3. c) Here are the standardized residuals from the chi-square analysis:

Discuss what the residuals show. What does this add to your answer in part b?
