Suppose the random variable X comes from some distribution with a mean μ and standard deviation σ. For a sufficiently large sample size, the sampling distribution of the sample mean is: (Select all that apply) - the same as the population distribution - centered at μ and has a standard deviation of σ - centered at μ and has a standard deviation of σ/∙n - approximately normally distributed - symmetric.

deviation than the population. To find the standard deviation of the sample mean σ_X̄, divide the population standard deviation σ by the square root of the sample size n. σ_X̄ = σ/√n
