   Question

   Suppose that in a population d is normally distributed with mean 63 and standard deviation 14. We draw from this population a sample of size n = 5. Then for the sample mean

   
   
   1. FALSE: Mean ~ N(μ = 12.6, σ = 2.8)
   2. FALSE: Mean ~ N(μ = 63, σ = 2.8)
   3. TRUE: Mean ~ N(μ = 63, σ = 6.26)
   4. FALSE: Mean ~ N(μ = 12.6, σ = 39.2)
   
   
   1. Mean ~ N(μ = 12.6, σ = 2.8): Incorrect
   2. Mean ~ N(μ = 63, σ = 2.8): Incorrect
   3. Mean ~ N(μ = 63, σ = 6.26): Correct
   4. Mean ~ N(μ = 12.6, σ = 39.2): Incorrect
