The Food and Drug Administration advises people against eating fish with mercury concentrations exceeding 1 part per million (ppm). Researchers wonder if the average mercury content of large-mouth bass in a certain state exceeds the limits and, thus, make such fish inedible.

They randomly sample large-mouth bass from randomly selected lakes in this state and record the amount of mercury in each fish. A p-value of 0.005 was obtained from a hypothesis test. Which of the following is a correct conclusion based on this p-value?

Sulfur dioxide affects human health when it is breathed in by irritating the nose, throat, and airways to cause coughing, wheezing, shortness of breath, or a tight feeling around the chest. The effects of sulfur dioxide are felt very quickly and most people would feel the worst symptoms in 10 or 15 minutes after breathing it in. Those most at risk of developing problems if they are exposed to sulfur dioxide are people with asthma or similar conditions (Australian Government, Sulfur dioxide (SO2) (Links to an external site.)Links to an external site.).

The United States Environmental Protection Agency has set a standard that sulfur dioxide (SO2) should not exceed 75 parts per billion (PPB) over a one-hour period. Fortunately, the United States has done a good job at reducing sulfur dioxide in the atmosphere.

To determine if the average SO2 of cities in the United States is less than 75 ppb, a random sample of 41 cities in the United States was taken. The average SO2 levels of the 41 cities was = 30.5 ppb.

(Note: the data used in this example is a bit old. SO2 levels have actually decreased more since these data were collected!)

Adina, age 32, is a married architect with one child. Her salary has reached a plateau at $85,000 a year. She believes that if she pursues an MBA degree full-time, she would move into a managerial position and her salary would rise by $60,000 a year. Adina wants to maintain her current lifestyle, which already generates substantial yearly cash savings and accumulate the capital to leave to her son. Her MBA course would take two years to complete and cost $52,000 a year. Because she plans to pay for the MBA out of existing savings and would be spending the money to qualify for a new position, she would not be eligible for any tax benefits. Assume that Adina pays one-third of her salary in taxes and her tax bracket will remain unchanged after the raise, that she can earn 6 percent after taxes on investments with a similar risk to her job, and that she plans to retire at age 65. Furthermore, assume that all salary and schooling payments are made in a lump sum at the beginning of each year. What is her rate of return on this investment? Should she pursue an MBA? If so, what will be the value of her human capital, assuming a calculation that incorporates salary forgone and her extra salary from obtaining her MBA upon graduation?

After reading the case that is below, How can a foreign company entering China ensure that it tackles the most important “little” things that end up being huge barriers to success as we approach the year 2020 when China is expected to have significantly increased purchasing power among its middle class?​ Write your opinion, as a manager, on how to face cultural issues like those described in the case, when entering foreign markets.

The People's Republic of China opened up to foreign investments in the late 1970s. Since that time, numerous companies have tried to establish operations and sell their products to customers in China. Many more companies will try in the years to come—China is expected to have some 190 million people in the middle- and upper-income categories by 2020. This is an increase from only about 17 million people in these income brackets as recently as in 2010. China's purchasing power for virtually all products and services has strong potential, and foreign companies will seek these market opportunities. What have we learned culturally that can help Western-based companies in China's marketplace?

Some background on China can serve as a starting point for better understanding the culture in China and what some well-known companies such as Best Buy and eBay have done to target the Chinese marketplace. The motivation for many foreign companies to enter China—beyond those that have been there for a few decades for reasons of low-cost production—was the triple growth of the Chinese economy that was seen from 2000 to 2010. China overtook Japan to become the second-largest economy in the world behind only the United States, and its large population makes for an enormous target market. Investment from foreign companies was the largest driver of China's growth in the decade from 2000 to 2010. However, many companies also increased their exports to China. The United States, for example, saw its companies increase exports to China by 542 percent from 2000 to 2011 (from about $16.2 billion to $103.9 billion), while total exports to the rest of the world increased by only 80 percent in the same time period.

Interestingly, while foreign investments grew, domestic consumption as a share of the Chinese economy declined from 46 percent in 2000 to 33 percent in 2010. This consumption decline—coupled with slower growth globally and, ultimately, the worldwide economic downturn that started in 2008—raised questions about China's momentum. Right now, around 85 percent of mainstream Chinese consumers are living in the top 100 wealthiest cities. By the year 2020, these advanced and developing cities will have relatively few customers who are lower than the middle- and upper-income brackets by Chinese standards. The expectation is that these consumers will be able to afford a range of products and services, such as flat-screen televisions and overseas travel, making the Chinese customer much more of a target for a wide variety of consumption. This begs the question, can the unprecedented Chinese growth really continue, and would it come from increased consumption?

The resounding answer is yes according to research conducted by McKinsey & Company. McKinsey found that barring another major economic shock similar to what we saw in 2008, China's gross domestic product (GDP) will continue to grow, albeit not at the historic levels seen between 2000 and 2010 when it grew about 10.4 percent annually. The growth from 2010 to 2020 is expected to be about 7.9 percent per year, which is still far above the expected growth for the United States (2.8 percent annually), Japan (1.2 percent annually), and Germany (1.7 percent annually)—the three countries among the top four worldwide economies along with China. And, the key is that consumption will now be the driving force behind the growth instead of foreign investment. The consumption forecast opens up opportunities for foreign companies to engage with Chinese consumers who are expected to have more purchasing power and discretionary spending.But culturally translating market success from one country or even a large number of countries to the Chinese marketplace is not necessarily as straightforward as it may seem. Often, a combination of naiveté, arrogance, and cultural misunderstanding have led many well-known companies to fail in China. Lack of an understanding of issues such as local demands, buying habits, consumption values, and Chinese customers' personal beliefs led to struggles for companies that had been very successful elsewhere in the world. Let's take a brief look at Best Buy and eBay as two examples.

Best Buy, the mega-store mainly focused on consumer electronics, was founded in 1966 as an audio specialty store. Best Buy entered China in 2006 by acquiring a majority interest in China's fourth-largest appliance retailer, Jiangsu Five Star Appliance, for $180 million. But culture shock hit Best Buy, best described by Shaun Rein, the founder of China Market Research Group. He pointed to a few reasons for this culture shock and lack of success. First, the Chinese will not pay for Best Buy's overly expensive products unless they are a brand like Apple. Second, there is too much piracy in the Chinese market, and this reduces demand for electronics products at competitive market prices. Third, like many Europeans, the Chinese do not want to shop at huge mega-stores. So, these three seemingly easy-to-understand cultural issues created difficulties for Best Buy. Solving these issues, Best Buy believed that it would have to develop and implement a different business model for the Chinese market than it has used, for example, in the United States. Now, how far should a company go outside its normal business model to adhere to cultural values and beliefs of a new market? Strategically moving forward, Best Buy opted to close all of its Best Buy–branded stores in China and focus on its wholly owned local Jiangsu Five Star chain of stores. But will this new strategic business model be successful with the new makeup of customers in China expected by 2020?

eBay, the popular e-business site focused on consumer-to-consumer purchases, was founded in 1995. The company was one of the true success stories that lived through the dot-com bubble in the 1990s. It is now a multi-billion-dollar business with operations in more than 30 countries. But China's unique culture created problems for eBay in that market. Contrary to the widespread cultural issues that faced Best Buy, one company in particular (TaoBao) and one feature more specifically (built-in instant messaging) shaped a lot of the problems that eBay ran into in China. Some 200 million shoppers are using TaoBao to buy products, and the company accounts for almost 80 percent of online transaction value in China. Uniquely, TaoBao's built-in instant messaging system has been cited as a main reason for its edge over eBay in China. Basically, customers wanted to be able to identify a seller's online status and communicate with them directly and easily—a function not seamlessly incorporated into eBay's China system. Clearly, built-in instant text messaging is a solvable obstacle in doing business in China. It sounds easy now when we know about it, but may not always be the case when we take into account all the little things that are important in a market.
