I need help figuring out parts c and d
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
![**Research Study Analysis: Examining the Relationship Between Military Branch and Blood Type**
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** | 134 | 74 | 43 | 24 |
| **Navy** | 99 | 80 | 59 | 22 |
| **Air Force**| 101 | 79 | 47 | 24 |
| **Marines** | 97 | 60 | 54 | 26 |
**Question:**
What can be concluded at the α = 0.10 significance level?
**a. What is the correct statistical test to use?**
- [ ] Paired t-test
- [ ] Goodness-of-Fit
- [ ] Homogeneity
- [ ] Independence
**b. What are the null and alternative hypotheses?**
\( H_0 \):
- [ ] Blood type and branch of the military are independent.
- [ ] The distribution of blood types is not the same for each branch of the military.
- [x] Blood type and branch of the military are dependent.
- [ ] The distribution of blood types is the same for each branch of the military.
\( H_1 \):
- [ ] The distribution of blood types is the same for each branch of the military.
- [ ] The distribution of blood types is not the same for each branch of the military.
- [ ] Blood type and branch of the military are independent.
- [x] Blood type and branch of the military are dependent.
**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.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F429495fa-514f-4d6e-b279-1e2d20094f9e%2Fcd3ee385-6d3e-4b98-90d8-8f9aefc22526%2Ft2y0o12_processed.jpeg&w=3840&q=75)
