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.
