The mean number of hours of part-time work per week for a sample of 317 teenagers is 29. If the margin of error for the populati

Shtirlitz [24]

Answer:

The degrees of freedom are given by:

$df=n-1=317-1=316$

And replaicing we got:

$29-2.1=26.9$

$29+2.1=31.1$

The 95% confidence interval would be between 26.9 and 31.1

Step-by-step explanation:

Information given

$\bar X= 29$ represent the sample mean

$\mu$ population mean

s represent the sample standard deviation

$ME= 2.1$ represent the margin of error

n represent the sample size

Solution

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

And this formula is equivalent to:

$\bar X \pm ME[/te]xThe degrees of freedom are given by:[tex]df=n-1=317-1=316$

And replaicing we got:

$29-2.1=26.9$

$29+2.1=31.1$

The 95% confidence interval would be between 26.9 and 31.1

A is in the shape of a quarter circle of a radius of 15cm. B is in the shape of a circle. the area of shape A is 9x the area of

RideAnS [48]

The radius of B is 2.5cm.

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a common point which is called the center of the circle.

Analysis:

Area of circle A = π $r^{2}$ /4 = π $(15)^{2}$ /4 = 225π/4

Area of circle B = π $r^{2}$

But A = 9B

225π/4 = 9 x π $r^{2}$

$r^{2}$ = 225/36 = 25/4

r = $\sqrt{\frac{25}{4} }$ = 5/2 = 2.5cm
