Question
Please help with is statistics questions. I don't know why my answers are wrong.
![### Hypothesis Testing Exercise
You wish to test the following claim at a significance level of \( \alpha = 0.005 \).
**Null Hypothesis (\( H_0 \)):** \( p = 0.38 \)
**Alternative Hypothesis (\( H_1 \)):** \( p > 0.38 \)
You obtain a sample of size 319 in which there are 142 successful observations.
**1. Test Statistic Calculation**
- **Question:** What is the test statistic for this sample? (Report the answer accurate to 2 decimal places but do not round in the middle of your calculations.)
**Answer Box:** [Input Box]
**2. P-value Calculation**
- **Question:** What is the p-value for this sample? (Report the answer accurate to 4 decimal places.)
**Answer Box:** [Input Box]
**3. Decision Based on Test Statistic**
This test statistic leads to a decision to:
- [ ] reject the null
- [ ] accept the null
- [ ] fail to reject the null
**4. Conclusion**
As such, the final conclusion is that:
- [ ] there is sufficient evidence to conclude that the population proportion is greater than 0.38.
- [ ] there is not sufficient evidence to conclude that the population proportion is greater than 0.38.
- [ ] there is sufficient evidence to conclude that the population proportion is equal to 0.38.
- [ ] there is not sufficient evidence to conclude that the population proportion is equal to 0.38.
