The owners of Phoenix Flames football team won different amounts of stock in the franchise, so when they vote on an issue they have different amounts of voting power. Assume that Alvarez’s and Cianci’s votes each will count twice, Belardo’s will be counted three times, Devlin’s four times, and Espinoza’s once. In order for a motion to be passed, the vote must be a total voting weight of at least nine. How many different subsets of this group of owners have a voting weight of at least nine?

- In a group of 5 freshman, 10 sophomores, 3 juniors, and 2 seniors, how many ways can a president, vice president, and treasurer be elected?arrow_forwardAt Southwestern Oregon Community College, a committee is being formed to decide on what kinds of facilities the new Health and Sciences building will include.Many of the campus community want a say in this matter, and 1515 members consisting of faculty, staff, administration, and student government have indicated that they would like to be a part of this committee. However, there are only 55 spots on the committee.Of the 1515 members of the campus community who want to be a part of this committee, 1010 are women and 55 are men.To decide who gets to serve on this committee, the 1515 names will be put into a hat, mixed up, and 55 will be drawn at random.(d) What is the probability that this committee consists only of women?(e) What is the probability that this committee consists only of men?(Note: please describe the methods you used to perform any of your calculations.)arrow_forwardThe city of Raleigh has 9500 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 350 randomly selected registered voters was conducted. 112 said they'd vote for Brown, 207 said they'd vote for Feliz, and 31 were undecided. a. What is the population of this survey? b. What is the size of the population? c. What is the size of the sample? d. Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown. e. Based on this sample, we might expect how many of the 9500 voters to vote for Brown?arrow_forward
- Alina, Robert, and Makayla are on the student council at their high school. They all want to go to a dinner where student council representatives from other schools will participate. However, only one student per school can go. How can a fair decision be made about who goes to the dinner? Select all that apply.arrow_forwardAll of the students in their final year of law school at the University of Memphis were sent an email asking them to participate in a research study. Forty law students volunteered for the study and provided informed consent. All of the participants observed a videotape of a crime. Next, a fair coin was flipped to decide if each participantwould go to a room on the right or a room on the left. The twenty students in the room on the right attempted to choose the criminal seen in the movie from a lineup consisting of five people. The twenty students in the room on the left chose from a lineup consisting of ten people. Each of the subjects then judged their confidence in the person they selected as the criminal from 50% (no idea) to 100% (completely sure). 4. What is the researcher’s hypothesis (Use your best guess if it is not obvious)? 5.
