Hello I Am Working On The Attached Case Study And Having Some Problems Getting T


I am working on the attached case study and having some problems getting the problem set up for questions 1,2, 3. I’m thrown off because there is no “N” value but I guess you don’t need it given the mean and std dev. I’m also a bit confused as well on if the x value. The first question refers to reducing the mean to meet the requirment but again, it’s sort of confusing. Could you help with this case?
