Question 196232: The graph and accompanying table shown here display 12 observations of a pair of variables (x, y).
The variables x and y are positively correlated, with a correlation coefficient of r = 0.96.
What is the slope, b, of the least squares regression line, y = a + bx, for these data? Round your answer to the nearest hundredth.
x 3 6 8 9 9 13 15 18 20 21 23 23
y 9 17 15 15 18 24 29 36 43 39 46 35

You can put this solution on YOUR website! The graph and accompanying table shown here display 12 observations of a pair of variables (x, y).
The variables x and y are positively correlated, with a correlation coefficient of r = 0.96.
What is the slope, b, of the least squares regression line, y = a + bx, for these data? Round your answer to the nearest hundredth.
x 3 6 8 9 9 13 15 18 20 21 23 23
y 9 17 15 15 18 24 29 36 43 39 46 35

I ran a Linear Regression Program on a TI calculator and found:
slope = 1.73482...
