Hello, you could find a nice and introductory example in the MINITAB blog "Explaining the Central Limit Theorem with Bunnies & Dragons" (http://blog.minitab.com/blog/michelle-paret/explaining-the-central-limit-theorem-with-bunnies-and-dragons-v2). You should take into consideration that the sum of random variables (known as convolution) is analytically complex for Weibull distributions. This has been asked here in RG before. See e.g. https://www.researchgate.net/post/How_can_I_calculate_the_convolution_of_two_Weibull_distributions
