Thread: [SOLVED] Easy stats question

I am having a hard time figuring out how to do this by hand, I understand the logic behind it but need someone to explain one thing.



I know how to find the numbers to make this on minitab but when I attempt to figure out how to convert 60 to a number that i can look up on the z tables.
