sx is the sample standard deviation and the other is the population standard deviation

The first part helped tremendously. I had been getting an error about syntax, and all I had to do was clear the memory. It works now. Thanks a lot.

[@jacquelineb7046]

This was really helpful, made it a lot easier. One minor detail, I think in your hand written note at the bottom you reversed the reference to n and n-1.

We have all sinned and fallen short of Gods glory sin is terrible because of sin we are separated from God but gladly here is the good news Jesus Christ came and walked this earth for everyone taught us the perfect way to live and how we should live and he died for our sins because we need a sacrifice to pay the price for our sins since our sins deserve hell if we live in sin but also more good news Jesus rose from the dead three days later we have to leave the sin behind and put it away and live new with Jesus this world is like a vapor it passes away but your eternity is forever and it is up to you what you want to do with it Jesus Christ is coming soon….
