I've been working on this problem for awhile and seem to be stuck. can someone please help me.....

The mean salary of the employees in a certain company is $22,300, with
a standard deviation of $2500. The company announces a flat raise of
$1000 for each employee during the following year. Find the mean and
the standard deviation of the new salaries.

Thank you

The mean increases by $1000 whereas the standard deviation remains the same.

Draw any distribution and imagine what would happen if the graph was shifted to the right. The mean would obviously shift as well, but the spread of the distribution would not change at all.

So if I'm getting this right my final answer would be a mean of 23,300 and standard dev. would be 2500?

Thank you for all the help!

There are complications that could result in a different answer, but your situation describes none such. I think you have it.
