As with all other distributions, the entire area under the curve will sum to 1. This area is also referred to as the cumulative probability and the formula to find the area is given below where Xo is a specific value of the random variable x. P(x SX0) = 1 - exo/u Here, we want to find the probability that the arrival time between vehicles is 13 seconds or less. Thus, x = and the probability statement is P(x s Submit Skip (you cannot come back) Need Help? Read It 15. [-/6 Points ] DETAILS ASWSBE14 6.E.037. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Intensive care units (ICUs) generally treat the sickest patients in a hospital. ICUs are often the most expensive department in a hospital because of the specialized equipment and extensive training required to be an ICU doctor or nurse. Therefore, it is important to use ICUs as efficiently as possible in a hospital. Suppose that a large-scale study of elderly ICU patients shows that the average length of stay in the ICU is 3.2 days. Assume that this length of stay in the ICU has an exponential distribution. (Round your answers to four decimal places.) (a) What is the probability that the length of stay in the ICU is one day or less
