Many attempts have been made to relate happiness with various factors. One such study relates happiness with age and finds that holding everything else constant, people are least happy when they are in their mid-40s (The Economist, December 16, 2010). Data are collected on a respondent’s age and his/her perception of well-being on a scale from 0 to 100; the data is presented below. Age Happiness 49 62 51 66 41 67 65 71 84 87 41 60 83 86...

The concept of statistics where we look at the amount and type of relationship that exists between two variables is the correlation. We can consider whether or how two variables are related to each other and how that relationship functions. For example, if you think that the more you study, the higher your grades will be, you are using correlation and prediction. You may have observed that as the number of hours you spend studying increases, so do your overall...

Eclipse Engineering provides services of structural engineering. They just opened a new branch in Portland, OR. One of their products is called Structural Insulated Panels, or SIPs. It is a type of foam insulation that replaces typical wall and roof framing for residential or commercial buildings. Clients are billed a fixed fee for each project based on square footage of the building, square footage of the panel area, and number of panels. Depending on how long a project takes to...
