Transcribed Image Text:### Hypothesis Testing: License Plate Law Violations Among Vehicles
#### Problem Statement:
Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.
**Context:**
Among 2073 passenger cars in a particular region, 222 had only rear license plates. Among 339 commercial trucks, 51 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.10 significance level to test that hypothesis.
You can test this claim by:
a. Using a hypothesis test.
b. Constructing an appropriate confidence interval.
#### a. Identifying the Hypotheses:
- **Null Hypothesis (H₀):** The proportion of passenger cars with only rear license plates is equal to the proportion of commercial trucks with only rear license plates.
- **Alternative Hypothesis (H₁):** The proportion of passenger cars with only rear license plates is less than the proportion of commercial trucks with only rear license plates.
Select the correct hypotheses from the options:
A. \( H_0: p_1 = p_2 \)
\( H_1: p_1 > p_2 \)
B. \( H_0: p_1 = p_2 \)
\( H_1: p_1 < p_2 \)
C. \( H_0: p_1 = p_2 \)
\( H_1: p_1 \ne p_2 \)
D. \( H_0: p_1 < p_2 \)
\( H_1: p_1 = p_2 \)
(Select the correct hypothesis by checking the appropriate box.)
#### b. Calculation Steps:
1. **Identify the test statistic:**
(Round to two decimal places as needed.)
2. **Identify the P-value:**
(Round to three decimal places as needed.)
#### Conclusion:
- **State the conclusion about the null hypothesis:**
- Reject \( H_0 \)
- Do not reject \( H_0 \)
(Select the correct option by checking the appropriate box.)
- **Final conclusion:**
- There is sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than

**Problem Statement:**
Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2073 passenger cars in a particular region, 222 had only rear license plates. Among 339 commercial trucks, 51 had only rear license plates. A reasonable hypothesis is that commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.10 significance level to test that hypothesis.
1. **Formulate the Hypotheses:**
- **Null Hypothesis (H₀):** There is no difference in violation rates of front license plates between commercial trucks and passenger cars.
- **Alternative Hypothesis (H₁):** Commercial truck owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
2. **Testing the Claim using a Hypothesis Test:**
*Identify the test statistic.*
- [ ] (Round to two decimal places as needed.)
*Identify the P-value.*
- [ ] (Round to three decimal places as needed.)
3. **Conclusion Regarding Hypotheses:**
*State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.*
- [ ] A. Reject H₀. There is sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
- [ ] B. Fail to reject H₀. There is sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
- [ ] C. Reject H₀. There is not sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
- [ ] D. Fail to reject H₀. There is not sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
4. **Testing the Claim using a Confidence Interval:**
*Identify the confidence interval limits for the appropriate confidence interval. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks.
