In a distribution with a mean of 50 and a standard deviation of 5:

15. What raw score corresponds with the 14th percentile?

16. What z-score cuts off the top 10% of this (or any) distribution?

17. What raw score cuts off the top 10% of this distribution?

18. What raw scores mark the middle 60% of this distribution?

 

I've been stuck on this for a while now. My teacher gave us one video to watch but it did not cover this so I don't know how to do this. Please help and show how to get the answer because I have over 30 of these questions. Thank you.

Here is a z score calculator.

There are others around if this one is inadequate.
