Let X be a random variable with mean µ and with variance o². You have a sample of size n with sample mean X and sample variance S² =E,(X; – X)²: n-1 1) Assume that X is equal to the average of the first 5 numbers in your dataset, and S² is equal to the sum of the first 5 numbers in your dataset. Further suppose that n is equal to
