Question

A fitness trainer is interested in investigating whether ethnicity and the first exercise activity that members engage in are dependent. The table below shows the results of the trainer's observation of randomly selected members.

Frequencies of Ethnicity and Exercise Activity

	Cardio	Weight Machines	Free Weights
White	99	95	90
Hispanic	81	100	91
Black	67	55	57
Other	47	49	62

What can be concluded at the = 0.05 significance level?

The test-statistic for this data = (Please show your answer to three decimal places.)
The p-value for this sample = (Please show your answer to four decimal places.)
The p-value is Select an answer greater than less than (or equal to)
Based on this, we should
- reject the null
- fail to reject the null
- accept the null
Thus, the final conclusion is...
- There is insufficient evidence to conclude that the distribution of first exercise activity is not the same for each ethnicity.
- There is insufficient evidence to conclude that ethnicity and first exercise activity are dependent.
- There is sufficient evidence to conclude that ethnicity and first exercise activity are dependent.
- There is sufficient evidence to conclude that ethnicity and first exercise activity are independent.
- There is sufficient evidence to conclude that the distribution of first exercise activity is not the same for each ethnicity.
