A simple linear regression of Y on X reveals that the slope b is 3; the standard deviation of X is 2; and the standard deviation of Y is 8. What is the correlation coefficient between X and Y? Show steps.
Homework Answers
The slope (b) can be calculated as follows:
b = r sY/sX
We can find 'r' from here
3 = r * 8/2
r = 0.75

Which of the following statements is true with respect to a simple linear regression model? a. The regression slope coefficient is the square of the correlation coefficient b. It is possible that the correlation between a y and x variable might be statistically significant, but the regression slope coefficient could be determined to be zero since they measure different things c. The percentage of variation in the dependent variable that is explained by the independent variable can be determined by...

True or false?: 1) If X and Y are standardized, then fit a linear regression line of standardized Y on standardized X, correlation between X and Y equals the slope of regression line. 2) If one calculates r for a set of numbers and then adds a constant to each value of one of the variables, the correlation will change. 3) The easiest way to determine if a relationship is linear is to calculate the regression line. 4) If the...
