Suppose the number of pages per book in a library has an unknown distribution with population mean 309 and population standard deviation 30. A sample of size n=50 is randomly taken from the population, and the sum of the values is taken. Using the Central Limit Theorem for Sums, what is the standard deviation for the sample sum distribution? Round your answer to two decimal places.
Answers: 3
