all you have to do is subtract

A drug company is testing a new drag which is supported to reduce blood pressure. From the nine people who are used as subjects,
Pie

Answer:

The 95% confidence interval for the mean change in blood pressure, \bar{x}, is 1.744 < \bar{x} < 2.816

Step-by-step explanation:

The parameters given are;

The number of people in the sample, n = 9

The average drop in blood pressure, \bar{x} = 2.28 points

The standard deviation, σ = 0.82

The confidence level = 95%

The formula for confidence interval with a known mean is given as follows;

CI=\bar{x}\pm z_{\alpha/2} \dfrac{\sigma}{\sqrt{n}}

Where:

z_{\alpha/2} = z - score at 95% confidence level = 1.96

We therefore have;

CI=2.28 \pm 1.96 \times \dfrac{0.82}{\sqrt{9}}

Which gives the 95% confidence interval for the mean change in pressure, \bar{x}, is given as follows;

1.744 < \bar{x} < 2.816
