Question
Which of the following involve Bernoulli trials? Pick one or more A geologist records the number of earthquakes over Richter magnitude 3.0 each year in California. A city is considering a noise control ordinance. A political pollster asks all the voters on a city block if noise is a significant problem in their city. A legal researcher takes a random sample of misdemeanor cases in city court, and notes whether each one goes to trial, charges are dropped, or is resolved by a plea bargain A medical researcher studying a type of cancer takes a random sample of patients, and for each patient records whether the patient survives five years. Overall the population probability of survival is p = 0.80.
Explanation / Answer
Bernoulli DIstribution Assumptions :
1 ) . Each trial results in one of two possible outcomes, denoted success (S) or failure (F).
2 ) The probability of Success remains constant from trial-to-trial and is denoted by p.
Write q = 1p for the constant probability of F.
3 ) The trials are independent.
so all the assumptions are satiesfied by Option D
So option D is correct
