Effectus [21]

Answer:

The value of the test statistic is of 0.22.

Step-by-step explanation:

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected mean, \sigma is the standard deviation(square root of the variance) and n is the size of the sample.

A lumber company is making boards that are 2920.0 millimeters tall.

This means that \mu = 2920.

A sample of 12 is made, and it is found that they have a mean of 2922.7 millimeters with a variance of 121.00.

This means that X = 2922.7, n = 12, \sigma = \sqrt{121} = 11. So

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{2922.7 - 2922}{\frac{11}{\sqrt{12}}}

t = 0.22

The value of the test statistic is of 0.22.

Radius= 4cm. find the area and diameter of the circle​
Bezzdna [24]
<h3>given:</h3>

radius= 4 cm

<h3>to find:</h3>

the area and the diameter of the circle.

<h3>solution:</h3><h3>diameter:</h3>

d = 2r

d = 2 \times 4

d = 8 \: cm

<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>diameter</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>circle</u><u> </u><u>is</u><u> </u><u>8</u><u> </u><u>centimeters</u><u>.</u>

<h3>area:</h3>

a = \pi {r}^{2}

a = \pi \times  {4}^{2}

a = 50.26548 \:  {cm}^{2}

a = 50.27 \:  {cm}^{2}

<u>hence</u><u>,</u><u> </u><u>the</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>circle</u><u> </u><u>is</u><u> </u><u>50.27</u><u> </u><u>square</u><u> </u><u>centimeters</u><u>.</u>
