Answer:

Explained below.

Step-by-step explanation:

According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normal.

Then, the mean of the sampling distribution of sample means is given by,

\mu_{\bar x}=\mu

And the standard deviation of the sampling distribution of sample means is given by,

\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}

So, if the sample of daily calcium intake of Americans collected is more than 30, then the sampling distribution of \bar X will be approximately normal.

yuradex [85]

Answer:

m = (f(4) - f(2)) / (4 - 2)

m = (24 - 10) / (4 - 2)

m = 14 / 2

Which word could describe the relationship of the lines containing the points (1, 6) and (1, 3)?
Elan Coil [88]

Answer:

Coincidental

Step-by-step explanation:

<em>If the two lines have the same two points, they must also have the same slope </em><em>and</em><em> the same y intercept. From this we can deduct that they are actually the same line. Two lines that are directly on top of each other are considered coincidental lines.</em>
