Use the Central Limit Theorem for Sums to find the sample mean and sample standard deviation Question Suppose weights, in pounds, of dogs in a city have an unknown distribution with mean 26 and standard deviation 3 pounds. A sample of size n = 67 is randomly taken from the population and the sum of the values is computed. Using the Central Limit Theorem for Sums, what is the mean for the sample sum distribution? Provide your answer below: pounds
