Need expert's help to confirm CRE Handbook 3E page 80 Example 6.6 step 4!

The step's result is correct, but it seems like that the specified calculation or using for F distribution table need to be confirmed as the attached picture.
From F distribution table: F(0.05, 20, 24)=2.03 , but F(0.95, 20, 24)=1/F(0.05, 24, 20)=1/2.08=0.48f486b5133dc8efe9ed6c835e67a85c18-huge-im

Zhipeng Zhu‍ I've moved this from the myASQ feedback board to this certification board in hope that an expert might help you. Dan Burrows‍ are you able to help or identify someone who might?

I will forward this to the CRE Handbook Team.

It may just be rounding from approaching it two ways.
