A clinical researcher performs a clinical trial on 12 patients to determine whether a drug treatment has an effect on serum glucose. The sample mean glucose of the patients before and after the treatment are summarized in the following table. The sample standard deviation of the differences was 8. Sample mean glucose (mg/dL)

![**Clinical Trial on Serum Glucose Levels**
A clinical researcher conducts a study involving 12 patients to evaluate whether a drug treatment influences serum glucose levels. The table below displays the average glucose levels of patients before and after the treatment. The sample standard deviation of the differences in glucose levels is 8.
**Table: Sample Mean Glucose Levels (mg/dL)**
| Treatment Stage | Sample Mean Glucose (mg/dL) |
|--------------------|------------------------------|
| Before treatment | 96 |
| After treatment | 91 |
**Hypothesis Test Details**
1. **Type of Hypothesis Test:** Options include:
- Left-tailed z-test
- Paired t-test
- Two-tailed z-test
- Unpaired t-test
2. **Test Statistic:** [To be filled by user]
3. **Number of Degrees of Freedom:** [To be filled by user]
4. **Significance Level:** To determine if there is sufficient evidence to claim the drug treatment has an effect on serum glucose at the \(\alpha = 0.01\) level. [To be filled by user]
This guide assists in determining the appropriate hypothesis test and evaluating the results based on the user's inputs.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0bd5c466-4067-47de-aefa-e4955ebdfa80%2Fb8622a35-1f30-4c4d-a37b-f2e450a9ed50%2F52o9icu_processed.png&w=3840&q=75)
