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: did u get an answer for that cuz if u did can u slide

To acquire approval to conduct an experiment with subjects from her undergraduate psychology course, a student researcher needs to submit an application to the university's institutional review board.
The purpose of the institutional review board review is to make sure that the appropriate steps are taken to protect the rights and welfare of subjects who are engaging in research, both beforehand and via ongoing assessment. Institutional review boards (IRBs) are tasked with reviewing all research involving human beings in order to protect their rights and welfare.
According to 45 CFR 46.103, the Institutional review boards must assess and approve any non-exempt human subject study. The researcher might not be allowed to use the data and other material gathered throughout the research process if the Institutional review board's permission was not obtained prior to performing the study.
