WNAE, an all-news AM station, finds that the distribution of the lengths of time listeners are tuned to the station follows the normal distribution. The mean of the distribution is 15.0 minutes and the standard deviation is 3.5 minutes. What is the probability that a particular listener will tune in: More than 20 minutes? (Round intermediate calculations to 2 decimal places. Round final answer to 4 decimal places.) For 20 minutes or less? (Round intermediate calculations to 2 decimal places. Round final answer to 4 decimal places.) Between 10 and 12 minutes? (Round intermediate calculations to 2 decimal places. Round final answer to 4 decimal places.)
