The following data show the amounts of a chemical compound y that dissolved in 100 grams of water at various temperatures x. Assume that the relation is linear and use Excel or other software to reproduce the estimated regression line and answer the following. Click here to view the table of chemical compounds. (Data can also be downloaded.) (a) The coefficient of determination for the regression can be found as R = (Round to two decimal places, including any zeros.) %3D (b) With 99% confidence, the population intercept parameter B, will be between (Round to three decimal places, including any zeros.) and and (c) With 99% confidence, the population slope parameter B, will be between including any zoros)
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 predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
