Answer:
a.) The Mean mu Subscript x overbarμxequals= μ
b.) The standard deviation sigma Subscript x overbarσxequals= σ overbar square root of n.
Therefore the sample mean is equal to the population mean, but the standard error of the mean on the other hand depends on the sample size.
We notice also, that as n increases, sigma x over barσx reduces. Therefore n is inversely proportional to sigma x barσx.
