Abstract

Annual wages of the employees are studied for their relation with several dependent variables to identify the most factors most impacting the variation in the annual wages. This paper attempts to analyze and establish the relationship of annual wages with the number of years of experience. Annual wages are considered to be a function of number of years of experience and there’s assumed to be a positive correlation. This paper tests the relationship using linear regression analysis method between the two variables. Annual wages is considered as the dependent variable and number of years of employment is taken as the ...

Abstract

In this case, we illustrate the application of multiple regression in economics. We gather data on the unemployment rate (dependent variable) and three independent variables; GDP per capita, maximum weekly unemployment benefit and population estimate for 2015. The data is collected from 39 different states. Regression analysis results show that there is a positive association between the unemployment rate and GDP per capita and population estimate. The relationship between unemployment rate and maximum weekly benefits is inverse. The evaluation of the reliability of the first-order model shows that it has a small coefficient of determination. The first-order model is ...

Essay #1. The research questions for this experiment involved the relative effectiveness of a shot and a nasal spray in keeping people from getting the flu. The hypothesis appears to have been that there would not be a significant difference between the two, with an eye toward proving that the nasal spray is just as effective as the shot. A nasal spray would be easier to deliver to patients and therefore more salable. 16 percent of the people who took the shot ended up getting the flu, while 24 percent got the flu in spite of the shot. This is a significant level ...
