Consider sampling heights from the population of all female college soccer players in the United States. Assume the mean height
Verizon [17]

Answer:

The approximated value of the standard deviation is 0.35.

Step-by-step explanation:

According to the Central Limit Theorem if we have an unknown population with mean <em>μ</em> and standard deviation <em>σ</em> and appropriately huge random samples (<em>n</em> > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally distributed.  

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

\mu_{\bar x}=\mu

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

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

The information provided is:

<em>n</em> = 100

<em>σ</em> = 3.5

<em>μ</em> = 66

As the sample size is quite large, i.e. <em>n</em> = 100 > 30, the central limit theorem can be applied to approximate the sampling distribution of sample mean by the Normal distribution.

Then the approximated value of the standard deviation of sampling distribution of sample mean is:

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

    =\frac{3.5}{\sqrt{100}}\\\\=0.35

Thus, the approximated value of the standard deviation is 0.35.

Q1:A circle has an area of 64π square inches. Which best represents the circumference of the circle?
SVETLANKA909090 [29]

Q1
————
16
π
Explanation:
To find the circumference of a circle, you need the radius.
Remember that the area of a circle is
A
=
π
r
2
Since we know the area, we can plug it in for
A
64
π
=
π
r
2

64
π
=
π
r
2

64
=
r
2
Take the square root of both sides to find the radius:
r
=
8
Now, use the circumference formula of
2
π
r
C
=
2
π
(
8
)
This simplifies to the circumference equalling

HELP ME PLEASE!!!!!!!!!!!!!
Lesechka [4]
Answer

There is a correlation (negative correlation in fact because patient numbers decrease with an increase in temperature or vice versa) between outside temperature and number of patient visits. There may or may not be causation. Further studies would have to be done to determine this.

There might be a causation factor because lower temperatures is associated with winter which is influenza season.

This means that it is reasonable to assume correlation may mean causation.

If it was let’s say a correlation between sales of ice cream and number of people drowning. There is no causation, as sales of ice cream don’t directly impact number of drowning incidents. It’s due to a hidden variable (temperature).
