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
Answer:
desertification
Explanation:
Desertification is a term that describes a form of environmental damage, most particularly in regions that are considered to have a low amount of rainfall. This is often caused largely as a result of human activities such as excessive crop cultivation, animal grazing, and the feeling of trees.
Hence, in this case, the environmental damage that occurs when plants and vegetation are subjected to too much animal feeding is referred to as DESERTIFICATION
