swat32
B. It’s bases are congruent

Explanation: A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.

Answer:

<h3>The standard error of the mean is <u>15</u></h3>

Step-by-step explanation:

Given that a simple random sample of 64 observations was taken from a large population.

Hence it can be written as n=64

The population standard deviation is 120.

It can be written as \sigma_{\overline{X}}=120

The sample mean was determined to be 320.

It can be written as \overline{X}=\mu =320

<h3>To find the standard error of the mean :</h3>

The formula for the standard error of the mean is given by

\sigma_{\overline{X}}=\frac{\sigma}{\sqrt{n}}

Now substitute the values in the formula we get

\sigma_{\overline{X}}=\frac{120}{\sqrt{64}}

=\frac{120}{8}

=15

\sigma_{\overline{X}}=15

<h3>∴ The standard error of the mean is 15</h3>
