Consider a 6-sided dice. The number on the face of a fair dice has a discrete distribution with a mean 3.5 and a standard deviation of 1.708. The average of 4 rolls of the dice is taken. If this was done many many times as in a sample of large n, the distribution is approx. Normal. What is the standard deviation of the sampling distribution of sample averages? State the answer to THREE decimal places only.
