The length of time (in seconds) that a user views a page on a Web site before moving to another page is a lognormal random variable with parameters 0 = 0.5 and w² = 1.44. (a) What is the probability that a page is viewed for more than 10 seconds? i (Round the answer to 4 decimal places.) (b) By what length of time have 50% of the users moved to another page? i seconds (Round the answer to 2 decimal places.) (c) What is the mean and standard deviation of the time until a user moves from the page? Mean = seconds (Round the answer to 2 decimal places.) Standard deviation = seconds (Round the answer to 2 decimal places.)
