Ecology: Hawaiian Tsunamis A tidal wave or tsunami is usually the result of an earthquake in the Pacific Rim, often 1000 or more miles from Hawaii. Tsunamis are rare but dangerous. Many tsunamis are small and do little damage. However, a tsunami 9 meters or higher is very dangerous. Civil Defense authorities sound an alarm telling people near the beach to go to higher ground. About 30% of all recorded tsunamis have been 9 meters or higher
(Reference Hawaii Data Book. Robert C. Schmitt). You are writing a report about X recent earthquakes in the Pacific Rim and you want to include a brief statistical profile of some possible
(a) Make a histogram of the
(b) What is the probability none of the tsunamis are 9 meters or higher?
(c) What is the probability at least one is 9 meters or higher?
(d) What is the expected number of tsunamis 9 meters or higher?
(e) What is the standard deviation of the r-probability distribution?

- Running Speed A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner’s time at the each of each lap, obtaining the data in the following table. (a) What was the man’s average speed (rate) between 68 s and 152 s? (b) What was the man’s average speed between 263 s and 412 s? (c) Calculate the man’s speed for cadi lap, Is he slowing down, speeding up, or neither?arrow_forwardIon Concentration The pH reading of a sample of each substance is given.
