...Population Trends in China Introduction China has been documented as the world’s most populous country, with a population of about 3 billion, which is about a fifth of the world’s population. The rapid growth in population has become a concern to the government, such that it has introduced various measures to curb the rate of growth. China therefore is a good case study in population growth trends, its analysis and prediction. This paper concentrates on population trends in China between 1950 and 2008, and outlines various models that could be used to represent the data. A...

...population, sample, parameter and statistic; concepts of population and sample Population refers to the set of all individuals which the researcher wishes to study. Sample is the group of individuals which is a subset of the population who are selected for the study. For the results of the study conducted on the sample to be held true for the entire population, the sample should be a representative sample – that is, it should possess the same characteristics as the entire population, or as close to it as possible. A statistic is a characteristic that describes a sample; a parameter is a characteristic that describes a population. The statistic for a sample usually corresponds in value... ? 2. Define...

...Problem a) I constructed the first linear function based on the municipal solid waste data for 1970 and 1997 and the second linear function based on the data for 1980 and 1997. A dependent variable is the annual production of municipal solid waste in million tons. An independent variable is the number of years after 1960.
Based on the municipal solid waste data from the graph, I received such numbers for independent and dependent variables for the models.

Looking at the data, one might say that it is not feasible for the company to be flying between the two cities as it implies a loss of $2000 (Total Revenue - Total Cost). However, rationality of the situation according to the economic analysis is that the firm should continue to operate and should fly between the two cities in the short-run. The rational behind this decision is the fact that in this case firm is covering all its variable costs and generating revenue which is greater than total variable costs. This means that firm...
