    Answer:

    Increase by 5% ;

    Remain unchanged

    Step-by-step explanation:

    Given that:

    Raise received by all workers = 5%

    Since the raise in salary cuts across all employees, then the average or mean salary will also increase by the same amount.

    y = m ± c

    y = new mean ; m = initial mean ; c = increase

    The standard deviation on the other hand isn’t affected due to change in a constant value. That is the standard deviation of a. Constant value is Zero. Hence, the standard deviation remains unchanged.
