If X is a random variable with a mean of 85.43 and a standard deviation of 17.23, what is the mean of the sample means calculated from samples of size 12 drawn from this population? Give your answer to two decimal places in the form xx.xx
I understand the mean is given and the standard dev is given for the random variable X. The part of the question I don't understand is the part where it says "mean of the sample means", how would you go about calculating the mean of the sample mean, if only a sample space is given, what kind of distribution method do I use?
