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
There was the humanist movement (the Renaissance)
the discovery of the new world ( Columbus)
and the french revolution
(sorry, i only know those 3)
We are what makes the earth. Our actions are what shapes the world and yourself. For an example: If everyone recycled we could reuse certain materials and make the earth less polluted. It's up to you to have the future of your planet be the way you want it to be.
