Biologists estimate that a randomly selected baby elk has a 44% chance of surviving to adulthood. Assume this estimate iscorrect. Suppose researchers choose 7 baby elk at random to monitor. Let X = the number that survive to adulthood.Does this scenario describe a binomial setting? Justify your answer.This is not a binomial setting. The probability of success is not the same for each trial.This is not a binomial setting. The number of trails are not fixed in advance.This is a binomial setting and X has a binomial distribution with n = 7 and p = 0.44.This is not a binomial setting. The given scenario is not binary.This is not a binomial setting. We cannot reasonably assume that the outcomes are independent.

A charity organization hosts a raffle drawing at a fund raising event. The organization sells 2500 tickets at a price of $8 each. Winning tickets are randomly selected, with 30 prizes of $100, 10 prizes of $500, and 1 grand prize of $8000. Suppose you buy one ticket. Let the random variable X represent your net gain from playing the game once ( net gain should include the cost of the ticket).
Use the results of the file. Recall that you performed a binomial probability experiment 50 times. In Project #3, you will calculate a 99% Confidence Interval for the true probability of success, a 95% Confidence Interval, and a 90% Confidence Interval. Which of these intervals contain your original guess? None of them? All of them? Was your original guess accurate or inaccurate? Write a paragraph to explain. the data is in the file

A project has a 60% of super success earning $50,000, a 15% chance of mediocre success earning $20,000, and a 25% probability of failure losing $30,000. What is the EMV of the project?
determine whether the given procedure results in a binomial distribution. if not, give the reason. Rolling a single die 34 times, keeping track of the number of 3s that are rolled.
Determine whether the given procedure results in a binomial distribution. If not, state the reason why. Rolling a single die 64 times, keeping track of the numbers that are rolled. O Not binomial: the trials are not independent. Procedure results in a binomial distribution. O Not binomial: there are more than two outcomes for each trial. O Not binomial: there are too many trials.
Determine whether the given procedure results in a binomial distribution. Tossing a coin 25 times and recording the number of tails you get.
When rolling two fair six-sided dice, getting a pair of 1s is called “snake eyes.” The probability of getting “snake eyes” on any roll is 1/36. Suppose that a game player rolls the two dice 80 times. Let X = the number of rolls that result in “snake eyes.” Find P(X = 2). Interpret this value in context.
A vaccine has a 87% probability of being effective in preventing disease. The probability of getting the disease if a person is not vaccinated is 46%. In a certain geographic region, 21% of the people get vaccinated. If a person is selected at random, find the probability that he or she will contract the disease. Round your answer to three decimal places. Also, draw a tree diagram or a table to support your work.
Determine if the following probability experiment represents a binomial experiment. If not, explain why. If the probability experiment is a binomial experiment, state the number of trials, n, and probability of success, p.
