Nice work! It's always good to see minimal applications that string different stacks together without going overboard with dependencies. Suggestion to the developer: Remove the "Calculate" buttons and update mean(), std() and cdf() after clicking "Generate". Repeatedly clicking Statistic's "Calculate" and getting different results (without updating the random numbers) is slightly confusing.
