A typo in the help files for compulsory exercise 2

In the proposed help file for compulsory exercise 2, there was a typo in the logistic function in the help listing for (g).

It should of course have been 

  1/(1+exp(-as.numeric(output))) there.

In case you have not corrected this yourself, the points won't be subtracted for (g) provided that you have shown an attempt to work on the problem. But great if you have noticed the error and fixed it in your assignment!
