H0: Ethnicity and Exercise Activity are independent.

H1:  Ethnicity and Exercise Activity are dependent.

The p-value is:

p-Value = ["0.015", "0.84", "0.042", "0.27"]      

Conclusion:

["There is insufficient evidence to make a conclusion about whether or not ethnicity and initial exercise type are independent."

["There is statistically significant evidence to support the claim that ethnicity and initial exercise type are dependent."]
