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
Option A
Cherokee group of North Georgia Indians was forcibly removed from its land after gold was discovered there
<u>Explanation:</u>
U.S. delegations, provoked by the state of Georgia, ousted the Cherokee Indians from their maternal motherland in the Southeast and transferred them to the Indian Region. The extraction of the Cherokees was an outcome of the need for the arable area through the widespread germination of renting in the Southeast, the invention of gold on Cherokee land.
Notwithstanding these works, white characters in Georgia and other southern states that adjoined the Cherokee Nation denied to believe the Cherokee people as cultural peers and pushed their political delegates to clinch the Cherokees' land.
The nomads used them to transport their loads and thus save themselves during desert journeys in Africa and the Middle East. Due to its endurance and ability to conserve water, the camel is the most suitable means of transport in the desert
