Is there an association between hair color and body type? The table below shows the results of a researcher's observations of randomly selected people.

---|---|---|---|
Short and Slender | 72 | 95 | 51 |

Tall and Heavy | 51 | 116 | 77 |
What can be concluded at the αα = 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 less than (or equal to) greater than αα
- Based on this, we should
- fail to reject the null
- reject the null
- accept the null
- Thus, the final conclusion is...
- There is insufficient evidence to conclude that the distribution of hair color is not the same for each body type.
- There is sufficient evidence to conclude that hair color and body type are independent.
- There is sufficient evidence to conclude that hair color and body type are dependent.
- There is insufficient evidence to conclude that hair color and body type are dependent.
- There is sufficient evidence to conclude that the distribution of hair color is not the same for each body type.

What conclusions can we come to by comparing the standard deviations of the males and females? c.
