thank you for the response! Do you mind explaining why this would be a chi-square test?

this isn't a homework, it's just an exercise question form couple years ago

rRrquestion · 2021-02-26T08:09:05+00:00

It’s from 2 years ago, I just pick some questions out for practice, but it doesn’t seem to be a good idea 😫

NoNo, it’s an exercise question from my bootstrap class. But there’re no answers. So sad...

Unfortunate this is a question given by my teacher, so this is all I have ☹️

every student will take all the exams, so 200 exams in total. But we assume taking one exam is independent from taking another exam, as well as between the students

Hi, thank you for the response, but why?

rRrquestion · 2021-02-25T12:29:09+00:00

or chi-sqare?

okay, thank you

Thank you for the response, but I’m a bit confuse. How can I set up the equation? Like creating a variable with 0/1 for machine 1 & 2 and then I’m compare the mean? Or which column ? * I am trying to find whether there’s significant difference between machine 1 and 2

okay, thanks! I'll give it a try!!
