Answer: 0.393
Explanation: If the given quantities are r-value (or Pearson's coefficient) and the standard deviations of x and y coordinates, we'll use the following formula for slope:
where:
m = slope of the best fit line
r = r-value = 0.793
= standard deviation of x-coordinates = <span>5.591
</span>
= standard deviation of y-coordinates = 2.772
So, the slope is calculated as follows:
Hence, the slope in 3 decimal places is 0.393.
