The histogram below shows the distribution of waiting times in minutes between 300 successive eruptions of a geyser.

Which one of the following is a valid conclusion from this histogram?The median time between eruptions is between 70 and 80 minutesThe distribution of times between eruptions is roughly log normalShorter intervals between eruptions are more likely than longer intervalsThe geyser has two sources erupting at different rates

Old Faithful is a cone geyser in Yellowstone National Park. A geyser is a natural fountain that shoots hot water into the air. Many tourists and scientists visit Old Faithful every year. Old Faithful is known for erupting water and steam at regular intervals. For eruptions that last about two minutes, it will spurt about every hour. For eruptions that last about four minutes, it will spurt about every hour and a half. Old Faithful will spray water from about 100 to 200 feet in the air. The geyser's water and steam come from underground. Earthquakes affect how often Old Faithful will erupt. What would be the best concluding sentence for this passage?*Hot springs are like geysers, but hot springs don't erupt water.Steamboat Geyser can spray water about 300 feet in the air.A group of people discovered Old Faithful in Wyoming in 1870.Old Faithful is one of the most famous geysers in the world.

Poisson processContd...Example 4: The reporting of customers at a counter in a railway station is a Poisson random process with mean rate of 3 customers in a minute. Find the probability that the interval of time between two consecutive customers is (i) more than a minute, (ii) between 1 and 2 minutes, (ii) at the most 3 minutes.

A sample of a radioactive material is studied in a lab. There are 1053 gamma ray emissions over 390 seconds.Use the Poisson distribution to find the probability that exactly 2 gamma rays are emitted in a single second.Do not round intermediate computations, and round your answer to three decimal places.(If necessary, consult a list of formulas.)
