Refer to the Baseball 2012 data, which report information on the 30 Major League Baseballteams for the 2012 season.
a. At the .05 significance level, can we conclude that there is a difference in the mean sal-ary of teams in the American League versus teams in the National League?
b. At the .05 significance level, can we conclude that there is a difference in the mean home attendance of teams in the American League versus teams in the NationalLeague?
c. Compute the mean and the standard deviation of the number of wins for the 10 teamswith the highest salaries. Do the same for the 10 teams with the lowest salaries. At the .05 significance level, is there a difference in the mean number of wins for the two groups?

Travelers pay taxes for flying, car rentals, and hotels. The following data represent the total travel tax for a 3-day business trip in eight randomly selected cities.
| 67.81 | 78.69 | 68.99 | 84.36 |
| 80.24 | 86.14 | 101.27 | 99.29 |
Use Minitab Express to construct the following confidence intervals. Report your answers rounded to three decimal places, where applicable.
a) We are 90% confident that the mean travel tax for a 3-day business trip to an American city is between $ _____ and $_____
b) We are 90% confident that the standard deviation travel tax for a 3-day business trip to an American city is between $_____ and $_____

Part 4A:(In 200 words) Using an American publicly traded company as an example describe what the graph would look like for the Straight-line depreciation method. Explain why the graph would visually represent the Straight-line depreciation method.
Part 4B:(In 200 words) (Using an American publicly traded company as an example) Using the straight-line method for amortizing a discount or premium, provide an example of the entry to issue a bond at par and the entry for the first 6 month interest payment. For each 6 month interest payment, explain why the interest expense amount is different (or the same) from the interest payment amount

A survey conducted for the Northwestern National Life Insurance Company revealed that 70% of American workers say job stress caused frequent health problems. Suppose a random sample of 10 American workers is selected.
What is the probability that more than seven of them say job stress caused frequent health problems?
What is the probability that exactly five say job stress caused frequent health problems?
What is the expected [mean] number of workers that would say job stress caused frequent health problems?

Many corporations take advantage of lower wages and production cost (and taxes) in other countries to produce less expensive products for the American market. The obvious solution is to bring those jobs and companies back to the United States. President Trump has touted such an approach. However, this transition would mean that the things we buy would be more expensive and affect the already tight budget of many Americans. So, here is another loaded question class...which way do we go? Cheaper products made overseas or more expensive products made stateside which bolsters the American job market?

Use the following to answer all of the questions. According to the Pew Internet and American Life Project 75% of American adults use the Internet. A survey of 600 adults aged 50-64 found 420 used the Internet (70%). We want to determine whether the proportion of Internet users age 50-64 differs from the overall proportion of 0.75. 1.What is the alternative hypothesis?
2. Compute the test statistic. Give answer to two decimal places.
3. Compute the p-value. Round answer to four decimal places.
4. If a=.05, what is the conclusion to the test? Reject Ho or Do not Reject Ho

A bridge on a small, rural road is designed to hold 10 cars when it is full and its maximum continuous weight that the bridge is designed to hold is 39,000 pounds. Assume that the average American car weighs 3750 pounds and that American cars' weights have a standard deviation of 200 pounds. If the bridge is fully loaded with 10 cars, what is the probability that it will be overloaded? Hint: Think about what the bridge designer thought the average weight of car that the bridge would hold would be and remember to draw a picture of the distribution to determine how you are treating the probability!
Do you think that the bridge in the previous question is safe to use? Why or why not?

After listening to the lecture, viewing the clips and reading the articles, the class should have an understanding of the global impact of the movement of the U.S. Dollar.
The current U.S. President has stated in strong and at times disparaging terms that the dollar was far too strong relative to our trading partners. Notwithstanding his comments and other factors since the beginning of the year, the dollar remains strong relative to other currencies.
Please discuss the following questions in your groups:
1. What are the implications of a strong dollar to U.S. trading partners?
2. How does this benefit or harm, American consumers?
3. Does it benefit American workers?
