A CBS News/New York Times poll of 1,000 adults in the United States asked the question, "Do you think global warming will have an impact on you during yourlifetime?" (CBS News website). Consider the responses by age groups shown below.AgeResponse18-2930+Yes134293No131432Unsure28a. What is the probability that a respondent 18-29 years of age thinks that global warming will not have an impact during his/her lifetime (to 4 decimals)?b. What is the probability that a respondent 30+ years of age thinks that global warming will not have an impact during his/her lifetime (to 4 decimals)?c. For a randomly selected respondent, what is the probability that a respondent answers yes (to 3 decimals)?d. Based on the survey results, does there appear to be a difference between ages 18-29 and 30+ regarding concern over global warming?

Exercise 1.4. There are two players. Each player is given an unmarked envelope and asked to put in it either nothing or $300 of his own money or $600. A referee collects the envelopes, opens them, gathers all the money, then adds 50% of that amount (using his own money) and divides the total into two equal parts which he then distributes to the players. (a) Represent this game frame with two alternative tables: the first table showing in each cell the amount of money distributed to Player 1 and the amount of money distributed to Player 2, the second table showing the change in wealth of each player (money received minus contribution). (b) Suppose that Player 1 has some animosity towards the referee and ranks the outcomes in terms of how much money the referee loses (the more, the better), while Player 2 is selfish and greedy and ranks the outcomes in terms of her own net gain. Represent the corresponding game using a table. (c) Is there a strict dominant-strategy equilibrium?
This problem involves empirical probability. The table shows the breakdown of 95 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is in the Army. Male Female Total Army 24 10 34 Navy 27 8 35 Marine Corps 5 1 6 Air Force 146 20 Total 70 25 95 The probability that a randomly selected single parent in the U.S. military is in the Army is (Type an integer or decimal rounded to the nearest hundredth as needed.)

When a new machine is functioning properly, only 6% of the items produced are defective. Assume that we will randomly select two parts produced on the machine and that we are interested in the number of defective parts found. (a) Describe the conditions under which this situation would be a binomial experiment. (Select all that apply.) For each part selected, the probability of a defective part being produced must be 0.06. The parts must be selected independently. The selection of a part is dependent on the first part selected. The number of successes and failures in this experiment are equal. The probability of choosing a part that is defective must be 0.94. (b) Draw a tree diagram similar to this section's example showing this problem as a two-trial experiment.
