1- Assume that when human resource managers are randomly selected, 38% say job applicants should follow up within

two weeks. If 6 human resource managers are randomly selected, find the probability that exactly 3 of them say job

applicants should follow up within two weeks.

2- Multiple-choice questions each have five possible answers (a, b, c, d, e), one of which is correct. Assume that you

guess the answers to three such questions.

a. Use the multiplication rule to find P(WCW), where C denotes a correct answer and W denotes a wrong answer.

3- An airline has a policy of booking as many as 15 persons on an airplane that can seat only 14. (Past studies have

revealed that only 86% of the booked passengers actually arrive for the flight.) Find the probability that if the airline

books 15 persons, not enough seats will be available.

Find the probability that not enough seats will be available.

4- The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random

variable x represents the number of girls among 8 children. Complete parts (a) through (d) below.

5- Assume that random guesses are made for 8 multiple-choice questions on a test with 2 choices for each question, so

that there are n = 8 trials, each with probability of success (correct) given by p=0.50. Find the probability of no correct

answers.

6- Determine whether the following procedure results in a binomial distribution or a distribution that can be treated as

binomial (by applying the 5% guideline for cumbersome calculations). If it is not binomial and cannot be treated

as binomial, identify at least one requirement that is not satisfied.

In a Pew Research Center survey of 200 subjects, the ages of the respondents are recorded.

7 - Based on a survey, when 1009 consumers were asked if they are comfortable with drones delivering their purchases,

42% said yes. The probability of randomly selecting 30 of the 1009 consumers and getting exactly 24 who are

comfortable with the drones is represented as 0+. What does 0+ indicate? Does 0+ indicate that it is impossible to

get exactly 24 consumers who are comfortable with drones?
