Question
![### Investigation of Blood-Pressure Drug Effectiveness
An experiment is being conducted to evaluate the effectiveness of a blood-pressure medication. The results indicate that the drug reduces systolic blood pressure by an average of 42 units in a sample of 30 individuals, with a standard deviation of 5.
**Objective:**
Estimate the expected reduction in systolic blood pressure for a typical patient when treated with this drug, using a 99% confidence level.
**Instructions:**
- Calculate and report the point estimate of the blood pressure reduction.
- Include the margin of error with your estimate.
- Provide your answers to one decimal place.
**Formula for the Confidence Interval:**
\[ \text{Confidence Interval} = \text{Point Estimate} \pm \text{Margin of Error} \]
### Calculation Section:
(Input fields for users to provide their calculated values)
**Point Estimate:**
\[ \boxed{\text{\[ \ \ \ \ \ \ \ \]}} \]
**Margin of Error:**
