What we are looking for is the confidence interval.
Given:
Sample it is denoted by n = 10
Mean = 80
Standard deviation = 12
Confidence Interval = 99%
Now compute for the margin of error, the formula is Za/2 * σ/√(n)
A 99% level of confidence has a critical value of zα/2 = 2.58.
The standard error is σ/√(n) = 3.162
Multiply 2.58 by 3.162 = 9.8 is the margin of error.
The formula for confidence interval is x̅ ± Za/2 * σ/√(n)
= 80 ± 9.8
= 70.2 < x< 89.8
I personal dont know the answer but its not C, i just did the test and got it wrong cuz i picked C.
Hope you find the answer!
The rebelled, boycotted, and stood for their rights as humans
The people of Earth face many problems
Struggling just to live and maintain peace.
There's differences in language, faith and race
With misguided hated unwilling to cease.
To solve these problems that plague mankind
We must strive as never before.
Demanding justice with truth in settling disputes
While recalling the loss and heartbreak of war.
War is an emotional release for man
Practiced since the first stones were cast.
Could it be nature's way of thinning the numbers
As the fallen are consumed by the past.
Some have asked why must we study history
It just encourages us to live in the past.
When we forget God and submit to whatever
The sorrows of our sins forever last.
I believe the answer is <span>material culture
</span><span>material culture refers to the touchable objects that people use to definte their cultures.
For examples, material cultures for japanese cultures would be Kimono, japanese temples, japanese foods, Katana, etc.</span>
