Which of the following are true about the correlation coefficient r? select one or more:
if the correlation coefficient is +1, then the slope of the regression line is also +1.
the correlation coefficient is always greater than 0.
if the correlation coefficient is close to 0, that means there is a strong linear relationship between the two variables.
the correlation coefficient will change if we change the units of measure.
the correlation coefficient is always between -1 and +1.
if the correlation coefficient is positive, the slope of the regression line will also be positive.
