A dataset of employee salaries shows a mean of $70,000 and a standard deviation of $10,000. If every employee receives a $5,000 raise, what will be the new mean and standard deviation of salaries?

✓ Correct Answer: Option B

Adding a constant value to every data point shifts the mean by that constant, so the new mean is $70,000 + $5,000 = $75,000. However, it does not change the spread or variability of the data, so the standard deviation remains $10,000.
