In Australia, young people aged 18 to 29 have an average of 394 Facebook friends. This population distribution takes only integer values, so it is certainly not Normal. It is also highly skewed to the right. Suppose that = 280 and you take an SRS of 70 Facebook users from this population. Findings from "Yellow social media report 2018 Part one-Consumers. published by Yellow and available at www.yellow.com.au/wp content/uploads/2018/06/Yellow-Social-Media-Report-2018- Consumer.pdf. For your sample, what are the mean and standard deviation of X, the mean number of friends per user? Use decimal notation. Give your answers to two decimal places if necessary.
