H1: Hair color and body type are independent. The distribution of hair color is not the same for each body type. Hair color and body type are dependent. The distribution of hair color is the same for each body type. C. The test-statistic for this data = (Please show your answer to three decimal places.) d. The p-value for this sample = (Please show your answer to four decimal places.) e. The p-value is (Select an answer f. Based on this, we should accept the null fail to reject the null reject the null g. Thus, the final conclusion is... There is sufficient evidence to conclude that hair color and body type are independe There is insufficient evidence to conclude that hair color and body type are depende There is sufficient 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 dependent There is insufficient evidence to conclude that the distribution of hair color is not the same for each body type.
