## Perform a chi-square test to determine if the type of medal and the country that earned it are independent of one another.

The table to the right shows the medal count for three countries following an international athletic event. Complete parts a. through c. below.

Medal

Country | Gold | Silver | Bronze |

A | 9 | 14 | 13 |

B | 9 | 13 | 8 |

C | 15 | 8 | 5 |

a. Using a = 0.025, perform a chi-square test to determine if the type of medal and the country that earned it are independent of one another.

Identify the null and alternative hypotheses for a chi-square test of independence

based on the information in the table. Choose the correct answer below.

A. Ho: Type of medal and country that earned it are independent of one another.

H1: Type of medal and country that earned it are not independent of one another.

B. Ho: Type of medal and country that earned it are not independent of one another.

H1: Type of medal and country that earned it are independent of one another.

C. Ho: Type of medal and country that earned it are independent of one another.

H1: The country that earns the medal affects the type of medal.

D. Ho: Type of medal and country that earned it are independent of one another.

H1: The type of medal affects the country that earned it.

Find the chi-square test statistic.

x2 = _ (Round to two decimal places as needed.)

Using alpha = 0.025, find the chi-square critical value, x2
