takes only inly not Normal. It is also highly skewed to the right, with a reported median of 200 friends. Suppose that σ= 380 and you take an SRS of 80 adult Facebook users. (a) For your sample, what are the mean and standard deviation of x, the mean number of friends per adult user? (b) Use the central limit theorem to find the probability that the average number of friends for 80 Facebook users is greater than 350.
