Hello Mathematicians I'm in dire need of help due to I'm new to statistics, and also it isn't my strong point in university Can someone tell me what formulas to use and how to put them out? And also would I need PHstat for Question 3 to be solved. And if so where do i get the latest version of it?Thanks alotPat P.S this isn't my actual assessment. They give us a practice one to do so we can pass in the in class exam which has waaaayyy more questions like the ones in the practice one Thanks alot guys again
