Math/STATS help!!

[.270]

I am taking a Graduate STATS class for my MS and I am stuck on this problem. I can't figure where to start. Any help would be greatly appreciated.

Given the mean is 300 and the standard deviation is 40, what T score represents the 70th percentile?

Much obliged!

No wonder Curt makes the big bucks

T score has a simple equation. I think you have everything there

I am not at home or I could possibly help.
I would search on YouTube for help or if you a ti 83/84 I believe you can press stat then scroll over until you find t score and input whatever info is needed. Hope this helps

Been a while since I've done that but there should be a formula or table in the back of your book.

If you are still stuck tomorrow, I'll check in with my son--PhD in Statistics.

Do you know your sample size or are you assuming 100 based on being 70th percentile?
