in statistics with numpy the practice exam : 3 question 2 i choosed the 4th answer but in the explanation of correct answer it says either i use minimum.reduce or min(text1 , axis=0 ) which i used but the the correct answer is different from both so now i'm confused ... can u pls check the practice exams there are many mistakes in different practice exams all over the course and maybe in other courses too ...

hey, the question asked for the minimum in the each columns, so we have to use the minimum. min function will return the minimum from the whole matrix. read the question more carefully

Don't be confused a lot of these practice and exam questions are misleading, subjective to user interpretation, or have multiple answers. Example: 2 out of the 4 options in this problem have identical results and the one they say is correct returns an error... I hope at the end of the career path the questions on our final exam are designed better or we have multiple tries to select incorrect answers like this one.
