Suppose X is a random variable whose distribution has mean 15.2 and standard deviation 29.1. If we draw random samples of size 30 from the population and take the mean of the sample values, these yield a new random variable X. For full marks your answer should be accurate to at least two decimal places. a) Find the expected value of X. b) Find the standard deviation X
