Question

A researcher is interested in investigating whether the military branch a person signs up for and the person's blood type are dependent. The table below shows the results of a survey.

Frequencies of Military Branch and Blood Type

	O	A	B	AB
Army	111	58	61	25
Navy	104	70	64	29
Air Force	129	67	53	27
Marines	130	67	65	21

What can be concluded at the αα = 0.10 significance level?

What is the correct statistical test to use?
- Independence
- Homogeneity
- Goodness-of-Fit
- Paired t-test
What are the null and alternative hypotheses?
H0:H0:
- The distribution of blood types is the same for each branch of the military.
- Blood type and branch of the military are dependent.
- The distribution of blood types is not the same for each branch of the military.
- Blood type and branch of the military are independent.
H1:H1:
- The distribution of blood types is the same for each branch of the military.
- Blood type and branch of the military are dependent.
- The distribution of blood types is not the same for each branch of the military.
- Blood type and branch of the military are independent.
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
- reject the null
- accept the null
- fail to reject the null
Thus, the final conclusion is...
- There is insufficient evidence to conclude that the distribution of blood types is not the same for each branch of the military.
- There is sufficient evidence to conclude that the distribution of blood types is not the same for each branch of the military
- There is sufficient evidence to conclude that blood type and branch of the military are independent.
- There is sufficient evidence to conclude that blood type and branch of the military are dependent.
- There is insufficient evidence to conclude that blood type and branch of the military are dependent.
