Reverse Engineering II

Math brain teasers require computations to solve.


Puzzle ID:#5928
Fun:** (2.05)
Difficulty:*** (2.93)
Submitted By:dewtell*us******




The formula discovered in "Reverse Engineering I" doesn't seem to apply exactly to many Braingle ratings once the number of voters gets larger. What is your best guess at the number of votes cast for each attribute of the following teasers prior to my vote, and how many of those were positive (fun/hard)? What do you think is the likely source of any "experimental error" between the formula and these reported ratings? (Notation is the same as in "Reverse Engineering I"). Multiple answers may be possible, because of the difficulty of determining how much of the reported data constitutes "experimental error."

Teaser M: (1.38, 1.20)[16] (+, -) -> (1.53, 1.13)
Teaser N: (2.00, 2.22)[18] (+, -) -> (2.11, 2.11)
Teaser O: (1.04, 2.82)[25] (-, +) -> (1.00, 2.87)
Teaser P: (2.13, 1.72)[44] (+, -) -> (2.17, 1.68)
