<p>I cannot figure out how the price is calculated. It is not the coupon divided by the yield. So what is it?</p>

Did you assume half the annual coupon every 6 months? I don't see the mean yield (only high, low, median) so I don't think you can calculate the mean price.

This page has yield conventions.  http://www.derivativepricing.com/blogpage.asp?id=12 It includes a “US Treasury” yield convention. I have not dug around the Treasury documentation to validate that this is the exact convention. In any event, it’s going to be close to the standard market convention.
