3. The makers of a soft drink want to identify the average age of its consumers. A sample of 25 consumers was taken. The average age in the sample was 32 years with a sample standard deviation of 5 years. Please answer the following questions: a. Construct a 95% confidence interval estimate for the mean of the consumers’ age. b. Suppose a sample of 51 was selected (with the same mean and the sample standard deviation). Construct a 95% confidence interval for the mean of the consumers’ age. 4. The ABC insurance INC. reports that the mean annual premium for automobile insurance in the United States was $1608 in summer 2018. However, you believed automobile insurance was cheaper in North Carolina and decided to develop statistical support for your opinion. A sample of 25 automobile insurance policies from the state of North Carolina showed a mean annual premium of $1560 with a standard deviation of s = $165.

a. Develop a hypothesis test that can be used to determine whether the mean annual premium in North Carolina was lower than the national mean annual premium.

b. At a = .05, test for a significant difference. What is your conclusion?

The Spread of Government Deposit Insurance Throughout the World: Is This a Good Thing? For the first 30 years after federal deposit insurance was established in the United States, only six countries emulated the United States and adopted deposit insurance. However, this began to change in the late 1960s, with the trend accelerating in the 1990s, when the number of countries adopting deposit insurance topped 70. Government deposit insurance has taken off throughout the world because of growing concern about the health of banking systems, particularly after the increasing number of banking crises in recent years (documented at the end of this chapter). Has this spread of deposit insurance been a good thing? Has it helped improve the performance of the financial system and prevent banking crises? The answer seems to be “no” under many circumstances. Research at the World Bank has found that, on average, the adoption of explicit government deposit insurance is associated with less banking sector stability and a higher incidence of banking crises. * Furthermore, on average, deposit insurance seems to retard financial development. However, these negative effects of deposit insurance occur only in countries with weak institutional environments: an absence of rule of law, ineffective regulation and supervision of the financial sector, and high corruption. This situation is exactly what might be expected because, as we will see later in this chapter, a strong institutional environment is needed to limit the moral hazard incentives for banks to engage in the excessively risky behavior encouraged by deposit insurance. The problem is that development of a strong institutional environment may be very difficult to achieve in many emerging market countries. We are left with the following conclusion: Adoption of deposit insurance may be exactly the wrong medicine for promoting stability and efficiency of banking systems in emerging market countries.

Discuss the positive and negative impacts of this type of insurance.

Write a program the declares and uses two parallel arrays. One array for storing the names of countries and a second array for storing the populations of those countries. As you can see per the following the Country name and it's corresponding Population are stored at the same element index in each array.

In the main method write a loop which asks the user if they would like to look up a given country's population.  

• If No, then terminate the program
• If Yes,
  • Call a value returning method, no parameters required:
    • This method prompts the user: What country would you like to look up?
    • The value entered is returned from this method
  • Call a second value returning method, passing it the value returned from the previous method call (ie. The name of the Country being searched for)
    • This method searches the country names array to see if it's there.
    • If it is there (ie it's found), return the population corresponding to the country
    • If it is NOT there, return a -1 which indicates the country was not found in the Country array
  • Back in the main method output the Country name searched for and it's population if found or Not Found when Not Found

i.e,

public class InClassModule_9 {

        public static String[] country = {"China", "India", "United States", "Indonesia", "Brazil", 
            "Pakistan", "Nigeria", "Bangladesh", "Russia", "Japan"};
        
        public static int[] population = {1367960000, 1262670000, 319111000, 252164800, 203462000, 
                        188172000, 178517000, 157339000, 146149200, 127090000};

        public static void main(String[] args) {

                System.out.println("Output/display contents from both arrays");
                for(int x=0; x < country.length; x++) {
                        System.out.println(x + ") Country: " + country[x] + "\tPopulation: " + population[x]);
                }
                System.out.println("\nThe End!!");

        }

Toys for children are made in numerous countries and then exported to buyers throughout the world. In some countries, such as the United States, certain protection exists to make sure that toys are safe for children. The U.S. Consumer Product Safety Commission (CPSC) regularly issues recalls of toys that have the potential to expose children to danger such as lead or other heavy metals. For example, lead may be found in the paint used on toys and in the plastic used to make the toys. If ingested (e.g., children chewing on toys), lead is poisonous and can damage the nervous system and cause brain disorders. Lead is also a neurotoxin that can accumulate in both soft tissue and bones in the body. For these reasons, lead was banned in house paint, on toys marketed to children, and in dishes or cookware in the United States in 1978. In addition, in an agreement between China’s General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) and CPSC, the Chinese agreed to take immediate action in 2007 to eliminate the use of lead paint on Chinese manufactured toys that are exported to the United States. With China’s prominence as a toy manufacturing country, this agreement was a step toward making safe products for children. Still, lead continues to be a hazard in a quarter of all U.S. homes with children under age six. In fact, a wide range of toys and children’s products, including many market-leading and reputable brands, often contain either lead or other heavy metals (e.g., arsenic, cadmium, mercury, antimony, or chromium). Estimates exist that suggest that one-third of Chinese toys contain heavy metals. This is a major problem given that China manufactures 80 percent of the toys sold in the United States. Researchers from Greenpeace and IPEN conducted a study by buying 500 toys and children’s products in five Chinese cities. They tested the products with handheld X-ray scanners and found that 163 of the toys were tainted with heavy metals above the norm (32.6 percent). “These contaminated toys not only poison children when chewed or touched, but can enter the body through the air they breathe,” said Ada Kong Cheuk-san at Greenpeace. While lead in the paint on toys has not been eliminated, the focus on cleaning up lead in the paint has been given front-page coverage ever since the agreement to eliminate it in 2007. It is certainly not gone, but at least more and more people are paying attention. Several organizations— both governmental and private—are examining lead-based paint in toys on a continual basis. For example, the New York Times and Consumer Reports recently found that dangerous products for children are still widely available. The Ecology Center has created a website called HealthyStuff.org that contains a database of toys and other products that have been tested for dangerous chemicals. While lead in paint seems to be in focus, the use of lead in plastics has not been banned! Lead is used to soften the plastic and make it more flexible to allow it to go back to its original shape after children play with the toys. Plus, lead may also be used in plastic toys to stabilize molecules from heat. Unfortunately, when the plastic is exposed to sunlight, air, and detergents, for example, the chemical bond between the lead and plastics breaks down and forms dust that can enter the human body. Another unfortunate part about lead is that it is invisible to the naked eye and has no detectable smell. This means that children may be exposed to lead from toys (and other consumer products) through normal playing activity (e.g., hand-to-mouth activity). As everyone with children knows, children often put toys, fingers, and other objects in their mouth, exposing themselves to lead paint or dust. Children are also more vulnerable to lead than adults; there is no safe level of lead for children. The worldwide toy industry has published a voluntary standard of 90 parts per million for lead in toys, which, of course, is greater than a ban on lead in paint used for toys and in the materials used to make the toys (such as plastics). But since 2007, the world has at least seen stricter standards—either voluntary or regulated standards—that make it safer for children to play with newly purchased toys. The CPSC in the United States, the European Union, and China’s AQSIQ are actively monitoring and seemingly enforcing stricter standards. But, according to Scott Wolfson of the CPSC, many toy manufacturers have been violating safety regulations for almost 30 years. So, are toys safer now than they were before 2007, and are they really safe to play with throughout the world? What do we do with the old toys? Sources: M. Moore, “One Third of Chinese Toys Contain Heavy Metals,” The Telegraph, December 8, 2011; P. Kavilanz, “China to Eliminate Lead Paint in Toy Exports,” CNN Money, September 11, 2007; U.S. Centers for Disease Control and Prevention. www.cdc.gov; “U.S. Prosecutes Importers of Toys Containing Lead, Phthalates,” AmeriScan, February 26, 2014. CASE DISCUSSION QUESTIONS 1. How realistic do you think it is to create a world standard for toys with respect to their safety and use by children? 2. Should we ban products from a country that does not follow standards similar to what the U.S. Consumer Product Safety Commission suggests for the United States? Is the CPSC overprotective? Should each country have its own guidelines? Why or why not? 3. If there are health risks associated with lead poisoning, what about related areas such as lead in drinking water (e.g., the issue that came to the forefront in the 2016 U.S. presidential campaign regarding water supply in Flint, Michigan)? 4. Is lead in toys a financial, or cost, issue? Why have we not seen the toy industry monitor and do something about the lead problem, even though we have known about it for more than 30 years?
