In a newspaper article, 28% of the 2600 adults polled said the U.S. space program should emphasize scientific exploration.

Calculate a lower confidence bound at the 99% confidence level for the true proportion of adults said the U.S. space program should emphasize scientific exploration. (2 Points)

Regardless of the true value of proportion, how large a sample size is necessary if the error at 96% confidence level is equal to 0.01? (2 Points)

The efficient market hypothesis states that it is impossible for investors to consistently beat the market. Is it also impossible for investors to consistently do worse that the market –

that is, it is possible to pick a bad portfolio of stocks that will do worse than the market? Explain. Ignore trading costs or fees paid to money managers.

b. Assuming that the U.S. Government will never default on its loans, is investing in U.S. government bonds completely riskless? Explain why or why not

Compared with Canada, Germany, and the U.K., the U.S. ranks first in the stock of medical technologies such as magnetic resonance imaging (MRI), radiation therapy, and cardiac catheterization. Typically, technological advancement is thought to reduce costs and thus leading to lower prices in most markets. However, in U.S. health care markets, technological improvements are cited as one of the reasons for price increases. Briefly explain this seemingly contradictory phenomena using supply and demand analysis.

Does anyone have experience with during a lab on conducting a 2-sample t-test at a 1% level of significance to find out if the U.S. stock returns significantly outperform the U.S. bond returns using the monthly data covering the sample period of 1980-2017? Draw conclusions by both the P Value and Critical Value Method.

Throughout most of the 1800s, the United States was a fairly isolationist nation especially in regards to not intervening in European affairs. Contrast the arguments made by leading isolationists and interventionists (expansionists) in the U.S. from the 1890s to the 1960s. Which side made the best argument overall and why? Should the U.S. have intervened in the conflicts it did (i.e. Spanish-American War, PhilippineAmerican War, World War I, World War II, and Vietnam) or not?

A Wall Street Journal (April 8,2014) article noted that a study by the U.S. Congressional Budget Office "estimated raising the minimum wages to $10.10 an hour would reduce U.S. employment by 500,000 but lift 900,000 Americans out of poverty." Why might raising the minimum wage reduce employment? How would it raise some people out of poverty? What effect might these estimates have on a normative analysis of the minimum wage?

A researcher was interested in utilities provided by city governments. The researcher randomly selected 20 counties from a list of all counties in the U.S. From each of these counties the researcher then contacted each city government (a total of 192) and found that 12 (6.25%) of them provided electricity to their residents. In this situation the sampling frame is

Select one:

b. the 316 cities.

c. the 20 counties.

d. 6.25%.

Tesla, Inc. is an American automotive company that specializes in electric car manufacturing. The company and Elon Musk, it’s current CEO, has been an innovator in the United States automobile industry. Tesla has used technology as one of it’s driving factors. They provide online software updates and have open source technology, to an extent. Tesla’s production efficiency and sales have increased the last few years. During 2018 & 2019, they were able to achieve some quarters profitability.

Despite of these improvements, the company has had to deal with a number of challenges. Among them:

Musk and the company were fined a total of $40 million dollars and Musk was not allowed to serve as Director of the Tesla Board for at least three years.
-   Although production has improved, it is still has not met expectations. The company has had many issues which include, assembly line issues, battery integration, and delivery logistics. During this time, Musk has made statements regarding production which has over promised to the market.
-   Tesla had achieved quarterly profitability for some quarters during 2018 and 2019. They had losses for years. Obviously, this is a problem but not unusual for a manufacturing company that takes a number of years to develop a market. The issue is that with accumulating debt, the unpredictability of production and costs have caused major concerns in the investor market place.
