![You are interested in investigating whether the type of computer a person primarily uses and the type of car they drive are dependent. The table below shows the results of a survey.
### Frequencies of Computer and Car Types
| | Sedan | SUV | Truck |
|--------|-------|-----|-------|
| Tablet | 90 | 91 | 40 |
| Notebook | 108 | 108 | 32 |
| Desktop | 106 | 94 | 21 |
What can be concluded at the \(\alpha = 0.10\) significance level?
a. What is the correct statistical test to use?
- [ ] Homogeneity
- [ ] Paired t-test
- [ ] Goodness-of-Fit
- [ ] Independence
b. What are the null and alternative hypotheses?
\(H_0\) :
- [ ] Computer type and car type are independent.
- [ ] Computer type and car type are dependent.
- [ ] The distribution of computer types is the same for each car type.
- [ ] The distribution of computer types is not the same for each car type.
\(H_1\) :
- [ ] The distribution of computer types is not the same for each car type.
- [ ] The distribution of computer types is the same for each car type.
- [ ] Computer type and car type are dependent.
- [ ] Computer type and car type are independent.
c. The test-statistic for this data = [______] (Please show your answer to three decimal places.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbed7ab37-3726-4b83-a741-6ed60a3ee8a9%2Fda747890-44b3-4db6-b2b8-8aac629937ee%2Fj7iodp9_processed.jpeg&w=3840&q=75)

c. The test-statistic for this data = [______] (Please show your answer to three decimal places.)
![The image contains a section from a statistical analysis task focusing on p-values and hypothesis testing. Here is the transcribed content:
---
d. The p-value for this sample = [______] (Please show your answer to four decimal places.)
e. The p-value is [Select an answer] α
f. Based on this, we should
- ( ) fail to reject the null
- ( ) reject the null
- ( ) accept the null
g. Thus, the final conclusion is...
- ( ) There is sufficient evidence to conclude that the distribution of computer types is not the same for each car type.
- ( ) There is insufficient evidence to conclude that computer type and car type are dependent.
- ( ) There is insufficient evidence to conclude that the distribution of computer types is not the same for each car type.
- ( ) There is sufficient evidence to conclude that computer type and car type are independent.
- ( ) There is sufficient evidence to conclude that computer type and car type are dependent.
