Arielle takes a random sample of the number of words on one page of her science book. She finds that one page contains 127 words. If the book is 200 pages long, approximately how many words are in the entire book? And explain how you got that answer.

Given a normal distribution with µ =50 and σ =4, what is the probability that 5% of the values are less than what x values? between what two x values (symmetrically distributed around the mean) are 95 % of the values? instructions: show all your work as to how you have reached your answer. don’t simply state the results. show graphs where necessary.
