1.) In the library on a university campus, there is a sign in the elevator that indicates a limit of 16 persons. In addition, there is a weight limit of 2,500 pounds. Assume that the average weight of students, faculty, and staff on campus is 155 pounds, that the standard deviation is 27 pounds, and that the distribution of weights of individuals on campus is approximately normal. Suppose a random sample of 16 persons from the campus will be selected.

a. What is the standard deviation of the sampling distribution of x bar?

b. What mean weights (in pounds) for a sample of 16 people will result in the total weight exceeding the weight limit of 2,500 pounds? The mean weight of 16 persons needs to be greater than _____lbs to exceed the weight limit of the elevator.

c. What is the probability that a random sample of 16 people will exceed the weight limit? (Use a table or technology. Round your answer to four decimal places.)

2. In a survey of 485 potential jurors, one study found that 340 were regular watchers of at least one crime-scene forensics television series. Assuming that it is reasonable to regard this sample of 485 potential jurors as representative of potential jurors in the United States, use the given information to construct a 95% confidence interval for the true proportion of potential jurors who regularly watch at least one crime-scene investigation series. (Use Table 3 in Appendix A. Give the answer to three decimal places.) ( ______, ________) please in this form.

3. In a survey of 1000 randomly selected adults in the United States, participants were asked what their most favorite and what their least favorite subject was when they were in school (Associated Press, August 17, 2005). In what might seem like a contradiction, math was chosen more often than any other subject in both categories! Math was chosen by 224 of the 1000 as the favorite subject, and it was also chosen by 366 of the 1000 as the least favorite subject.

(_____, .2498)

4. Many consumers pay careful attention to stated nutritional contents on packaged foods when making purchases. It is therefore important that the information on packages be accurate. A random sample of n = 12 frozen dinners of a certain type was selected from production during a particular period, and the calorie content of each one was determined. (This determination entails destroying the product, so a census would certainly not be desirable!) Here are the resulting observations, along with a boxplot and normal probability plot

the values are

a. Carry out a formal test of the hypotheses suggested in part (b). (Use Table 4 in Appendix A. Use α = 0.05. Round your test statistic to two decimal places and your P-value to three decimal places.)

t= ___

df= 11

P= ___

please answer all parts, i appreciate it.

1. Discuss whether the following are strong arguments. If you consider them weak, explain why.

1. We need to protect American jobs. Therefore, we need stricter laws to keep illegal aliens from crossing the United States–Mexico border.
2. We shouldn’t be making such a big deal about football players and concussions. After all, look at all the people, especially kids, who get concussions falling off their bicycles and no one is arguing that we should ban bicycles!

3. People need to pass a driving test to get a license to drive a car. People should also have to take a parenting test and get a license before they can have a child. After all, parenting is a greater responsibility and requires more skill than driving.
4. We should allow fraternities on our campus. After all, they provide volunteers to do a lot of charitable work.
5. My dog Rex growls only at people who are untrustworthy. Rex growled at Bob when he brought me home after our date. Therefore, I should not trust Bob.
6. If you’re going to buy a new car, you should buy a Toyota Camry. They’re one of the safest cars on the road, according to Consumer Reports.
7. Abdul is a freshman at state community college. All freshmen at state community college are residents of Texas. Therefore, Abdul is a resident of Texas.

Good argument

8. Marijuana use should be legal in the United States. After all, both Presidents Barack Obama and George W. Bush as much as admitted that they had used marijuana.
9. God is all powerful. God is all good. Terrible things happen to people through no fault of their own. Therefore, God does not exist.
10. You should stay away from Gloria because she’s a troublemaker.

2. Identify the unstated premise(s) in each of the following arguments. Evaluate each of the arguments. Does leaving out the premise weaken or change the argument?

1. Maria is a single mother. We should reject her application to the pre-med program.
2. Buck’s father is a successful doctor and a graduate of State University. Buck should do well in the pre-med program.
3. If you want to save money, buy your textbooks on Amazon.com instead of the college bookstore.
4. Cats don’t bark. Therefore, Friskie doesn’t bark.
5. If you’re traveling in Europe you should buy a rail pass instead of renting a car.
6. I hear you’d like to do a semester in an African country. Given that the only languages you speak are Portuguese and German, you should consider doing an internship in Angola or Mozambique.
7. I wouldn’t trust Ben around children. I hear he was abused as a child.

1. Identify the conclusion and premises in the argument in this advertisement. Evaluate the argument.

2. What is the objective of this ad? Is the ad effective in meeting its objective? Discuss the strategies, including rhetorical devices and fallacies,

Pick any 2 questions and answer it ( answers should be half page long per question):

1.Bill Gates is a founder of Microsoft and the world's richest individual. Suppose Microsoft sells more software and Mr. Gates acquires another billion dollars in wealth. Simultaneously, suppose a burglar whose income is well below average broke into Bill Gates' house and stole a million dollars worth of antiques. Using the "it's not fair if the rules aren't fair" approach to fairness, is Mr. Gates' acquisition of additional wealth fair? Is the (poor) thief's acquisition fair?

2. What is your opinion on price ceilings in the market for gasoline? Price ceilings were last imposed in the 1970s: To help ration gasoline, drivers were allowed to buy gasoline only on certain days. If the car had an even numbered license plate, the driver could buy on even numbered days and vice versa for cars with odd numbered license plates. (On the 31st of a month, anyone could buy gasoline.) But gas stations sold gasoline for only a limited number of hours per day and it typically took 60 minutes to get gasoline. The station would indicate it was selling gasoline by hoisting a green flag; when it stopped selling that day, the station showed a red flag.

3. Healthy economy caused a positive relationship between wages and employment. Explain.

4. Widely scapegoated by the general public and our elected officials as the greedy profiteers responsible for the recent economic collapse, high-income corporate executives have been made potential targets for federally mandated compensation limits. Do you believe that companies should be allowed to determine how much to pay their workers, or if the federal government should get to decide?

5. The level of income over which people pay no tax has been rising over the last decade, so nowadays many people’s incomes fall below the level at which the income tax is imposed. In fact, after deductions, exemptions, and credits about 47 percent of all tax filers in the U.S. actually pay zero (or even negative) income taxes, whereas the top 1 percent of taxpayers pay about 40 percent of all the income taxes and the top 10 percent pay about 70 percent. Do you think this trend is fair or unfair? What do you predict will happen if the trend continues?

6. During 2007, as oil and gas prices continued to increase, a growing number of Americans called for the United States to become less reliant on Middle-Eastern oil. Would it make sense for the United States to try to become totally self-reliant in the production of oil? Why or why not?

You should explain the confidence intervals you create along with explanations of the meaning of your answers and business implications for each problem.

Scenario:

You have been asked once again to study the mean tuition at private universities throughout the United States. You will also again study the proportions of universities throughout the United States that regularly award more than 50% of their students some form of financial aid. The specific questions you will be asked to answer are stated below. In addition, appropriate sample data for the studies you will be accomplishing is given below. Answer the following questions concerning the situations posed.

The organization for which you are working in your study of private university tuition has been quite impressed with your work. Its CEO has a relative who works for the Major-League Baseball Players’ Union. Your services and abilities have been recommended to union leadership. You have been asked to perform a study that will result in a comparison of the average salaries per player for major league baseball teams. This information will be needed as historical data to be used in upcoming labor negotiations. The average player salary data for two recent years for all 30 major league baseball teams is shown below in appendix two. At the 1% level of significance, has the average player salary increased from the first year to the second year? For the purposes of the study, you may assume that this data is sample data drawn from a much larger population of teams. Once again, should the procedure you choose to accomplish this task allow for it, construct a 99% confidence interval for the difference in the mean salary per player from year one to year two. Explain the meaning of this interval.

As a policy instrument, currency devaluation may be controversial since it:

On May 23, 2013, a 160-foot span of the Skagit River Bridge on I-5 north of Seattle collapsed moments after upper bridge supports were struck by a tractor trailer with an oversized load. The truck made it safely across, but two other vehicles fell into the water 24 feet below. Three people were rescued without major injuries. The bridge was constructed in 1955 and designed for an expected life of 50 years.

The Skagit River Bridge is rated by the Federal Highway Administration (FHWA) as functionally obsolete—it is not designed to today’s standards, but it is not necessarily unsafe. The steel element could cause collapse. There are about 18,000 fracture critical bridges throughout the United States, build mostly between the mid-1950s and late 1970s. Modern construction methods are much more resilient to damage.

In 2007, the I-35W bridge carrying traffic over the Mississippi River between Minneapolis and St. Paul collapsed suddenly during rush hour, killing 13 people and injuring 145. The Minnesota bridge, completed in 1967, was also a fracture critical bridge and was classified as structurally deficient by the FHWA. Structural deficiency indicates that the bridge has one or more defects in its support structure or deck and therefore requires maintenance, repair, and eventual rehabilitation or replacement.

The nation’s 611,845 bridges have an average age of 43 years, and almost 23% are rated as either structurally deficient, functionally obsolete, or both. The FHWA calculates that more than 30% of U.S. bridges exceed their 50-year design life. The required fiscal investment for reconstruction and renovation poses a significant challenge for federal, state, and local governments—but some progress is being made. Decisions on how to allocate funding to upgrade and replace deficient bridges are influenced by both economic and non-economic factors.

• The Skagit River Bridge carries an estimated 71,000 vehicles a day and is a main commercial route between the United States and Canada. How would you calculate the economic impact of the catastrophic failure of the bridge? Compare the economic impact to commuters versus commercial traffic.
• What factors should be considered when engineers determine whether to either rehabilitate or replace a deficient bridge?
• The Federal Highway Administration released $1 million in federal emergency funding the state of Washington the day after the I-5 bridge collapse and almost a month later allocated $15.6 million in federal funding to help rebuild the bridge. Discuss the ethical dilemma of state and local governments that have aging infrastructure to repair before tragedy strikes, but insufficient funding to make the repairs.
• Both of the bridges described here were routinely inspected and deemed safe for use. Discuss how this inability to predict structural failures complicates the job of transportation officials.
