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
A true because it is and plz give me a thank cause i got you the right answer.

Explanation: According to research by Fergus I.M. Craik and Endel Tulving on levels of processing. Memorization can be improved by semantic processing meaning it provides meaning or context to the word.(In dept processing)

As a result of the above, memory traces are formed which contains code characteristics and continues to remain in the memory.
A cognitive analysis must be conducted during the deeper dept of processing which will help to retain the character.
