My code is the same as in the solution video. Is it a bug that i can´t get a correct answer? I tried even to line the first numbers row parallel with each other but didn´t manage. Can anyone help me to get a correct answer?

Please print out ONLY the final values of the mean

and the variance in a list [mu, sig].

Your output should be

[10.999906195879419, 4.0058651026392962]

you should print only the last result of mu and sig. Do not change the location of the original print command.

Thanks for the answer. But then the video of Pr. Thrun is not correct, because he asks to print exactly as he does !!! Who did not pay attention to the requests ?

I also had to change the code of the update function a little bit to

... 1./(1./var1 + 1./var2)

before the answers were correct. Otherwise it seemed to return integers for the variance.
