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
