= 43 and n, Consider two populations for which u, = 38, o, = 3, lz = 27, and o, = 2. Suppose that two independent random samples of sizes n, selected. Describe the approximate sampling distribution of x, - x, (center, spread, and shape). = 52 are What is the shape of the distribution? O The distribution would be non-normal. O The distribution is approximately normal. O The shape cannot be determined. What is the mean of the distribution? What is the standard deviation of the distribution?
