Listed Below are amounts of bills for dinner and the amounts of tips thet were left. is there sufficient evidence to conclude that there is a linear correlation between them? Bill: 33.46 50.68 87.92 98.84 63.60 107.34 Tips: 5.50 5.00 8.08 17.00 12.00 16.00 D. Use a significance level of to decide if there is sufficient evident to support the claim that the two variables have a linear correlation. E. Find the equation for the lienar regression line, or line of best fit through the data when presented in scatterplot. F. Use regression equation to predict the tip amount for a dinner bill of $100.00 G. What tipping rule does the regression equation suggest? Technically the tipping rule says multiply the total bill by ?
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.
