Let the interval of time between the eruptions be normally distributed with standard deviation 16 minutes. Complete parts (a) through (e) below. (a) What is the probability that a randomly selected time interval between eruptions is longer than 88 minutes? The probability that a randomly selected time interval is longer than 88 minutes is approximately 0.3085 . (Round to four decimal places as needed.) (b) What is the probability that a random sample of 9 time intervals between eruptions has a mean longer than 88 minutes? The probability that the mean of a random sample of 9 time intervals is more than 88 minutes is approximately 0.0668 . (Round to four decimal places as needed.) (c) What is the probability that a random sample of 26 time intervals between eruptions has a mean longer than 88 minutes? The probability that the mean of a random sample of 26 time intervals is more than 88 minutes is approximately (Round to four decimal places as needed.)
