If a company has five employees with annual salaries of $50,000, $60,000, $50,000, $70,000, and $90,000, respectively, what is t

To find mean, simply add up all 5 salaries to get 320,000. Then divide by 5 to get the average salary of $64,000
The sequence is not arithmetic
The margin of error is 1.41.
The margin of error is calculated using the formula
where z is the z-score associated with the confidence level, σ is the standard deviation, and n is the sample size.
For a confidence level of 95%, we find the z-score by first converting the percent to a decimal and subtracting it from 1:
1 - 0.95 = 0.05
Divide that by 2:
0.05/2 = 0.025
This is the area in each tail.
Subtract this from 1 again, since we want the area between the tails:
1 - 0.025 = 0.975
Looking this up in the z-table (http://www.z-table.com) we see that the z-score is 1.96.
Using our information, we have:
