[size=4]Suppose the mean and standard deviation of serum iron values for healthy men are μ =110 and σ =13 micrograms (mg) per 100 ml. If x[sup]-[/sup] [/size][size=4]is the mean of serum iron of a random sample of size 36 healthy men, then:[/size]

[size=4]By the central limit theorem the sampling distribution of  x[sup]-[/sup] is approximately:
