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:

<span>Prior to the standard gauge track, railroad travel was much more arduous and painstaking. There were originally several types of gauges used on a railway track. This caused long train trips to require multiple stops in order to change train cars. With the standard gauge track on trains in the 1800s, multiple changes were no longer necessary and so the trips were shorter.</span>
You think some more about what happened on your way home. You realize that your colleague is but one person; who knows how many other people out there think like her?

What policies exist to stop such institutionalized prejudice?
