Question

Use tables for the standard Normal distribution to find the required values of z. P( Z < z ) = 0.3345. From the table I can find P(Z < z) for any z, nothing else. How can I then find z?

Answer 1

So look along your table for the point where P(Z<z)=0.3345 and then see which value of z this corresponds to.

Answer 2

It's close to values in another table I found but the exercise explicitly stated that I should use the table provided where I can find only P(Z < z), P(Z < -z or Z > +z ), P(Z > z), see attached image. I however don't see how it's possible to find it exactly?

Answer 3

Have you been told specifically to use that graph?

Answer 4

I'm sorry, it's true that I was told specifically to use the graph but apparently I didn't understand how to use it. Found a setting that was incorrectly configured. Thank you.

Answer 5

Ah ok :)
