Americans should learn to live without these two imported products. But, they should not have to give up these two imported products. Justify your reasons for each statement.(8-10 sentences)

This is a sample response to help clarify the question:

The first important import that the US should be able to live without is crude oil. The US produces a large percentage of the oil it needs and only needs roughly 25% more to meet its demand. If the US can cut its usage by that last 25% or so, we would be able to be self-sufficient and not have to rely on other countries for this import. Thirty seven percent of the energy the US consumes is from petroleum, increasing the usages of natural gas and renewable sources, not only will the US benefit but also the environment will as well.

The US should be able to live without importing automobiles. I say this because motor vehicles is one of the top imports of the US at the same time as being the number three ranked export. I like the ability for a consumer to buy what they like with the amounts of cars to choose from. However, there are so many domestic cars, ranging from economy cars to large luxury vehicles. If these are such a good export, we should be able to live with not bringing in cars from other countries and look to drive American made cars.

The two products that I think Americans should not have to live without are somewhat similar. Both are beverages, but enjoyed differently. The first is real good Columbian grown coffee, sometimes it is the best part of getting out of bed in the morning! The US imports about $6.3 billion in coffee each year, which is the highest at 19%. As we tend to be labeled as work-aholics, coffee is a big player is keeping us on the go. The second import I think Americans should not have to give up is the import of beer. Beer is made with such cultural influences, and some of the best beers around are imported. I have been to Germany twice, and I will say, their beer is unmatchable. Even with the increase in craft brewing in the US, ending the importing Canadian beers, European beers and Mexican beers is just something I do not want to ever see.

We wish to predict the salary for baseball players (yy) using the variables RBI (x1x1) and HR (x2x2), then we use a regression equation of the form ˆy=b0+b1x1+b2x2y^=b0+b1x1+b2x2.

• HR - Home runs - hits on which the batter successfully touched all four bases, without the contribution of a fielding error.
• RBI - Run batted in - number of runners who scored due to a batters's action, except when batter grounded into double play or reached on an error
• Salary is in millions of dollars.

The following is a chart of baseball players' salaries and statistics from 2016.

a) Use software to find the multiple linear regression equation. Enter the coefficients rounded to 4 decimal places.
ˆy=y^=  +  x1x1 +  x2x2  

b) Use the multiple linear regression equation to predict the salary for a baseball player with an RBI of 49 and HR of 22. Round your answer to 1 decimal place, do not convert numbers to dollars.
millions of dollars

c) Holding all other variables constant, what is the correct interpretation of the coefficient b1=0.111b1=0.111 in the multiple linear regression equation?

• For each RBI, a baseball player's predicted sallary increases by 0.111 million dollars.
• If the baseball player's salary increases by 0.111 million dollars, then the predicted RBI will increase by one.
• If the baseball player's salary increases by 0.111 million dollars, then the predicted RBI will increase by 0.0371.
• For each HR, a baseball player's predicted sallary increases by 0.111 million dollars.

d) Holding all other variables constant, what is the correct interpretation of the coefficient b2=0.0371b2=0.0371 in the multiple linear regression equation?

• If the baseball player's salary increases by 0.0371 million dollars, then the predicted HR will increase by one.
• For each RBI, a baseball player's predicted sallary increases by 0.0371 million dollars.
• If the baseball player's salary increases by 0.0371 million dollars, then the predicted HR will increase by 0.111.
• For each HR, a baseball player's predicted sallary increases by 0.0371 million dollars.
