![**Title: Analysis of Drug Effectiveness on Cholesterol Levels**
A drug manufacturer claims that a new drug lowers cholesterol levels in patients studied. The following data shows the levels of cholesterol in 5 patients before and after taking the drug. Assume the data is normally distributed. Is there enough evidence to support the claim at a 0.02 level of significance?
**Data Table:**
| Patient | 1 | 2 | 3 | 4 | 5 |
|---------|-----|-----|-----|-----|-----|
| First Attempt | 224 | 235 | 219 | 224 | 215 |
| Second Attempt | 227 | 229 | 207 | 218 | 200 |
**Tasks:**
1. Complete the table.
2. Find the standard deviation of the difference \( s_d \).
This exercise involves comparing cholesterol levels from two different attempts (before and after drug administration) to identify any significant reduction and determine the standard deviation of the differences. This analysis will help evaluate the effectiveness of the drug at lowering cholesterol levels at a 0.02 level of significance.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa39be845-ae1d-44f6-957a-0c42c0fe4c23%2F88c359f5-efe0-44da-a456-ab91ac0b907d%2Ff4wf0b_processed.jpeg&w=3840&q=75)
