In ancient civilization, the individuals with varying physical appearance were fill member of the society by adopting the cultural norms.

<h3>What is physical variation?</h3>

It should be noted that the physical variation means the range of values for the mental and physical characteristics of human beings.

Classical variations invested the most importance in tribal affiliation rather than the physical appearance.

Also, societies still equate physical characteristics like eye and hair color.

Anthropologists conclusion about human race is that there are no human biological races.

Suppose that a jewelry store tracked the amount of emeralds they sold each week to more accurately estimate how many emeralds to
RUDIKE [14]

Answer:

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

And for this case the 95% confidence interval is given by (2.13; 2.37)

We have a point of estimate for the sample mean with this formula:

\bar X = \frac{Upper+ Lower}{2}= \frac{3.37+2.13}{2}= 2.75

And for the margin of error we have the following estimation:

ME= \frac{Upper -Lower}{2}= \frac{3.37-2.13}{2}= 0.62

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

\bar X represent the sample mean

\mu population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size  

Solution to the problem

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

And for this case the 95% confidence interval is given by (2.13; 2.37)

We have a point of estimate for the sample mean with this formula:

\bar X = \frac{Upper+ Lower}{2}= \frac{3.37+2.13}{2}= 2.75

And for the margin of error we have the following estimation:

ME= \frac{Upper -Lower}{2}= \frac{3.37-2.13}{2}= 0.62

The Mason High Cougars need to win 3 out of the next 12 baseball games to make it to
natta225 [31]

Answer:

The percent for 3 out of 12 is 25%

If the total number of games was 100, the win amount would need to be 25.

Step-by-step explanation:

3 out of 12 is a fraction - 3/12

3/12 = 0.25 which means 25% because 0.25 is 25% of 1.

Using the same percentage for 100 total games, you just multiply 100 by 0.25, the decimal version of the percentage.
