    Do you mean x bar?

    mean of 106 inches and a standard deviation of 10 inches and for sample of size is 25. Determine the mean and the standard deviation of /x

    If so, x bar equals the population mean. So it's 106.

    Sample standard deviation = Population standard deviation / square root of n
    10/Sqrt(25)
    10/5
    2
