It is said that the 'b' coefficient should be between -1 and +1; But in the video the co-efficient 1.67. I wish to understand why. Thank you.

You are probably referring to the correlation coefficient, which is indeed between -1 and +1 (see lesson "Correlation coefficient"). Coefficients in a simple linear regression model, however, can take any value. Furthermore, for the same dataset, the correlation coefficient and regression coefficient will have the same sign (+ or -). But the values have different meanings. I hope this help.
