To determine A graphical display of the following data sets, choosing any type of display that we feel is appropriate and explanation for our choice of display and discussion of any interesting features in the data. Explanation Given: Make a graphical display of the following data set, choosing any type of display that you feel is appropriate. Explain your choice of display and discuss any interesting features in the data. The following table gives the number of daily newspapers and their total circulation (in millions) for selected years since 1920 . Year Number of Daily Newspapers Circulation (millions) 1920 2042 27.8 1930 1942 39.6 1940 1878 41.1 1950 1772 53.9 1960 1763 58.8 1970 1748 62.1 1980 1747 62.2 1990 1611 62.3 2000 1485 56.1 2010 1390 45.2 The use of computer graphics has helped to advance multidimensional plots; in particular three-dimensional graphs. The three-dimensional graphics are the one that are shown with all the three dimensions of figure drawn. The advantage of three-dimensional graphics is that they allow us to show richer data sets. The drawback is that it can be difficult to read the data precisely. The following figure is a three- dimensional graph; thereby it shows distinct information along its three axes...

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

3. Suppose you have 12 professors in a department and you have to chose members of departmental committees. (a) How many ways can you pick members for one 4 people committee? (b) How many ways can you pick members for two different 4 people committees if no-one can serve on both committees? (c) How many ways can you pick members for two different 4 people committees if people can serve on both committees? (d) How about if you need members for a 4 person, a 5 person, and a 3 person committee, people cannot serve on more than one committee? (e) How about if you need members for a 4 person, a 5 person, and a 3 person committee, people can serve on more than one committee? (f) How about if you need members for a 4 person, a 5 person, and a 3 person committee, people cannot serve on more than one committee, and the first person chosen for each committee serves as chair?
