Volatility on Binomial Trees for Valuing Bonds

Per practice question 2 p. 363 on CFA book, are we supposed to be able to calculate the yields at various nodes. For example, in year 3 Nhhh, the yield at 10% volatility is 9.2% but at 20% volatility it is 12% (see page 388). I believe the yields at each nodes will be provided to us, I hope??

I believe so, I remember I had the same question when I was reading thrugh… I don’t recall seeing details on how to calculate yields from volatility.

As far as I know, they give you the yield at each node.
