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

A park has a large circle painted in the middle of the playground area. The circle is divided into 444 equal sections, and each

balu736 [363]

Answer:

The area of each section of the circle is $A=25\pi\ m^{2}$

Step-by-step explanation:

we know that

Each section represent a quarter of circle

The area of a quarter of circle is equal to

$A=\frac{1}{4}\pi r^{2}$

we have

$r=10\ m$

substitute

$A=\frac{1}{4}\pi (10)^{2}$

$A=25\pi\ m^{2}$
