Explanation Given info: The data related to the size of new HD flat panel televisions to predict the cost. The four possible slopes of the regression line are 0.03, 0.3, 3 and 30. Calculation: Answer will vary. One of the possible answers is given below: Generally TV screen sizes vary from 19 inches to 70 inches. Assume that size of a TV screen is 20 inches. It is known that TV costs are generally measured in thousands of dollars. For slope 0.03: The predicted cost for a TV with screen size 20 inches is 20 ( 0.03 ) = 0.6 . Thus, the predicted cost for a TV with screen size 20 inches is $60. For slope 0.3: The predicted cost for a TV with screen size 20 inches is 20 ( 0.3 ) = 6

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…
