# Using interpolation (probability) watch

1. I'm looking at the example given and I don't understand how to get one of the numbers.

'o' is meant to be 'phi'

o(0.278)=o(0.27)+0.8 x (o(0.28)-o(0.27))=0.6099.

From looking at the tables, I'm not sure how to get 0.8

Can someone explain it to me please?
2. It's like saying 0.278 is 80% into the interval (0.27, 0.28).
Does this help?

A simple "No" would have sufficed instead of neg-repping.

I didn't neg rep you. There is no reason to and I have been pos-repping you in the previous questions you helped me with... I also got negged. I would pos-rep you but I can't anymore for some reason.

And with regards to the question, it did help so thanks.
5. That's ok! Glad to have helped.

I didn't neg rep you either. Someone just playing games here I suppose!
