Suppose that the length of research papers is uniformly distributed from 9 to 22 pages. We survey a class in which 55 research papers were turned in to a professor. We are interested in the average length of the research papers.Give the distribution of ΣX. (Round your standard deviation to three decimal places.)Calculate the probability that the professor will need to read a total of more than 920 pages. (Round your answer to four decimal places.)Find the probability that an individual paper is longer than 16 pages.Find the probability that the average length of 55 papers is more than
