DIRECTIONS: Ask for the probability of a randomly selected item being less than a value that is larger than your mean(please show me the steps in how this is solved ) I sampled 8 books and found the mean length (# of pages) to be 276 with a sample standard deviation of 34 pages. Find the probability that a randomly selected book has less than 150 pages.
