Sample means from a infinite population
A population has mean of 60 and a standard deviation of 5. A random sample of 16
measurements is drawn this population. Describe the sampling distribution of the
sample mean by computing its mean and standard deviation
"\\mu_{\\bar X}=\\mu=60."
"\\sigma_{\\bar X}=\\frac{\\sigma}{\\sqrt{n}}=\\frac{5}{\\sqrt{16}}=1.25."
