In a private subreddit people are posting their opinions on the CEO of the company you work for. Lets assume that the employees that are posting are random logging in to that subreddit and that each post indicates whether the employee approves or not the job that the CEO is doing. Let x; be the binary random variable where x₁ = 1 indicates approval. You can assume that æ is distributed according to a Bernoulli distribution with parameter p = 1/2. Your job is to sample n = 50 posts and estimate the approval rate of the CEO by considering the statistics of y = x₁ + x2 ++. What is the probability that 25 employees approve the CEO? Following your findings in Q1a, read about the Cenral Limit Theorem and recognize that y-Hy oy z = is normally distributed with mean 0 and variance 1. Can you find the probability that 25 employees approve the CEO using the Gaussian approximation? Type the answer here using the latex syntax or handwrite the answer, upload the picture in the same folder and use a new markdown cell with markdown syntax !
