   Question

   For a sample size of n = 5 from a population with a mean $\mu$ and standard deviation $M$, the distribution of sample means $M$ follows a normal distribution with mean $\mu$ and standard deviation $$frac{sigma}{sqrt{n}}$ . . .

   
   
   1. FALSE: Regardless of the shape of the distribution of the variable in question.
   2. FALSE: If the sample mean $M$ and the standard deviation $s$ are unbiased (unbiased).
   3. FALSE: If the sample is randomly drawn and representative of the population.
   4. TRUE: If the variable of interest in the population is normally distributed.
