**Investigating the Effectiveness of a Blood Pressure Drug**An experiment is conducted to evaluate the effectiveness of a blood-pressure drug. The findings indicate that, on average, the drug reduces systolic blood pressure by 42 units in a sample size of 30 individuals, with a standard deviation of 5.**Objective:** Estimate the reduction in systolic blood pressure for a typical patient using this drug with a 99% confidence level.**Instructions:**Provide your answers to one decimal place. The results should include the point estimate together with its margin of error.**Answer Format:**```[Point Estimate] ± [Margin of Error]```**Input Fields:**- [Point Estimate: __ _ . _]- [Margin of Error: __ _ . _]

The sample mean is 42, the sample standard deviation is 5 and the sample size n is 30.

Answered: The effectiveness of a blood-pressure…
