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
