Suppose that the average number of Facebook friends users have is normally distributed with a mean of 135 and a standard deviation of about 46. Assume forty-four individuals are randomly chosen. Answer the following questions. Round all answers to 4 decimal places where possible. What is the distribution of ¯x? ¯x ~ N(___,___) For the group of 44, find the probability that the average number of friends is less than 134. Find the first quartile for the average number of Facebook friends. For part b), is the assumption that the distribution is normal necessary? Yes or No
