Complete parts (a) through (e) below. DUN (a) What is the probability that a randomly selected time interval between eruptions is longer than 107 minutes? The probability that a randomly selected time interval is longer than 107 minutes is approximately (Round to four decimal places as needed.) (b) What is the probability that a random sample of 11 time intervals between eruptions has a mean longer than 107 minutes? The probability that the mean of a random sample of 11 time intervals is more than 107 minutes is approximately (Round to four decimal places as needed.)
