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

- Upward
- Unilateral
- Downward
- Bilateral
This is an example of upward comparison. In this example, Wendy judges her performance by comparing it to that of other members of her team. However, she compares herself with those who did better than her. This is known as upward comparison. When a person compares himself to those who are worse off, this is a case of downward comparison.
When a prosecutor makes a plea bargain they agree to make a deal if the defendant pleads guilty to specific charges, in return for specific concessions from the prosecutor. In jurisdictions with either the common law adversarial system or the civil law inquisitorial system, a prosecutor is a legal representative of the prosecution.
In a criminal trial, the prosecution is the legal party in charge of presenting the case against a person accused of breaking the law. The prosecutor typically represents the state or the government in the case brought against the accused. Prosecutors are often lawyers with a law degree who have been approved by the court.
