Suppose x has a normal distribution with mean μ = 35 and standard deviation σ = 9.
(a) Describe the distribution of x values for sample size n = 4. (Use 2 decimal places.)
μx =
σx =

(b) Describe the distribution of x values for sample size n = 16. (Use 2 decimal places.)
μx =
σx =

(c) Describe the distribution of x values for sample size n = 100. (Use 2 decimal places.)
μx =
σx =
