Why might it be helpful to calculate from a bunch of random samples drawn from the empty model of the DGP? Responses A Because the mean of the sampling distribution will tell us what the true of the population is.Because the mean of the sampling distribution will tell us what the true beta sub 1 of the population is. B Because the resulting sampling distribution would give us an idea of how much sample from a random DGP could vary.Because the resulting sampling distribution would give us an idea of how much sample b sub ones from a random DGP could vary. C Because this helps us fit the best fitting normal curve over our sample distribution.Because this helps us fit the best fitting normal curve over our sample distribution. D Because if the resulting sampling distribution is roughly normal, that proves that our sample came from a normally distributed population
