This is AP Statistics Question. Can you help me with this?
LenKa [72]
The confidence interval is given by

\mu_s\pm Z_{\alpha_0}\sigma_s

where \mu_s is the sample mean and \sigma_s is the standard error of the mean. In turn, the standard error of the mean is \sigma_s=\dfrac\sigma{\sqrt n} where n is sample size.

We have

\sigma_s=\dfrac6{\sqrt{25}}=1.2

The endpoints of the confidence interval correspond to the finite endpoints of the rejection region. That is,

\begin{cases}\mu_s-1.2Z_{\alpha_0}=28\\\mu_s+1.2Z_{\alpha_0}=32\end{cases}

for which we can solve for Z_{\alpha_0}. We get

Z_{\alpha_0}=\dfrac53\approx1.67

which is the critical value for a confidence level of \alpha_0\approx90.44\%.

Positive angles located in the fourth quadrant may be described as___.
gladu [14]

Answer:

Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360 .</u>

The option is

4. 270≤Ф≤360

Step-by-step explanation:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

For Example.

Quadrant I    - 0 to 90°

Quadrant II   - 90° to 180°

Quadrant III  - 180° to 270°

Quadrant IV - 270° to 360° ( 4. 270≤Ф≤360  )

Hence,Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360 .</u>

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV  -          0° to -90°

Quadrant III   -      - 90° to -180°

Quadrant II    -      -180° to -270°

Quadrant I     -      -270° to -360°
