# Math Help - [SOLVED] Easy stats question

1. ## [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.

You're expected to know that $Z = \frac{X - \mu}{\sigma}$.

3. nm...found it just after I posted too..

z = y - mu / sigma

thanks mr fantastic btw
