Linear regression on all Anscombe data
Now, to verify that all four of the Anscombe data sets have the same slope and intercept from a linear regression, you will compute the slope and intercept for each set. The data are stored in lists; anscombe_x = [x1, x2, x3, x4] and anscombe_y = [y1, y2, y3, y4], where, for example, x2 and y2 are the \(x\) and \(y\) values for the second Anscombe data set.

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Iterate through x,y pairs
for x, y in zip(____, ____):
# Compute the slope and intercept: a, b
a, b = ____
# Print the result
print('slope:', a, 'intercept:', b)
