Let $\eta$ be a random variable that takes the value $0.5$ or $-0.5$ with equal probability $0.5$..Define $\theta_n= \dfrac{\sum_{i=1}^n \eta_i}{\sqrt{n}},$ where $\eta_i$ are independent variables with the same distribution as $\eta.$ Find the values that $\theta$ can take and their probabilities for $n= 3,6,9.$ Plot their histograms together with the pdf of the limit of $\theta \text{ as } n \rightarrow \infty.$
The problem is when I choose a very big $n,$ $\theta$ doesn't seem to converge to any value I just keep getting random values at each try.
density=True
as an argument to the plot function. I'm not sure about plotting $\theta_n$ $\endgroup$
