VARVARA [1.3K]

The mean of sample means is the same as the mean of the underlying distribution.


The standard deviation of sample means is the original distribution sample mean divided by the square root of the number of samples.


Mean of sample mean distribution: 64

SD of sample mean distribution: 4/√64 = 1/2

Identify the property being shown here, assuming that a + 2 = y. <br> (a + 2)/3 = y/3
allochka39001 [22]

Assuming that <em>a + 2 = y</em>, the property that was applied to arrived at <em>(a + 2)/3 = y/3</em> is the: division property of equality.

<em><u>Recall:</u></em>

What is done to both sides of an equation will determine what property of equality was applied to the equation.

  • Thus, given the equation:

a + 2 = y

  • The following was obtained:

(a + 2)/3 = y/3

Observing the equation stated above, we will see that both sides of the equation was divided by three. This makes both sides equal.

Therefore, assuming that <em>a + 2 = y</em>, the property that was applied to arrived at <em>(a + 2)/3 = y/3</em> is the: division property of equality.
