Regression Characteristics of the line of best fit What is error in relation to the line? What are components to determine a regression line? A How to calculate B How to calculate Y-hat How to calculate X

Linear Regression Model  Discuss the following: i. Interpret the coefficients (a and b) of the regression equation in context. Comment on whether the value of a makes sense in the context of your data. ii. Interpret 2 r r squared   For this question I have the equation and the coefficients of r and r squared  they are as follows: y-hat =-166.65403 + 4.7387237x R (correlation coefficient) = 0.53095364 R-sq = 0.28191177

In the regression equation, what does the letter X represent? Multiple Choice The dependent variable The independent variable The Y-intercept The slope of the line

Question Help Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful.
